Is your muffin buttered?

I used to blog. Then I stopped that to have a more professional-looking puzzle site with lots of authors. My brain didn’t stop having the thoughts I would have blogged. They got put elsewhere or shot off into the void.

I rarely use social media, and almost never now, particularly as the truth is up for consensus decree. I wonder if the world can look not round in those cool RayBans.

But still, I hear there are some doggies that are looking to make the world better through e-fishin’-c. Here are some ideas if a doggie comes up to you:

1. Make mental health care available across state lines without conditions or at least allow for “vacations”. Seriously, if I travel out of state A, I cannot speak to my therapist or psychiatrist from state A unless they are licensed in the state B that I am now physically present in. I’ll accept that I shouldn’t have the right to purchase firearms because I’ve been hospitalized for being bipolar if you’ll accept that my relationships with my doctors and therapists are the most important in my wellness circle and your laws are in the way of my best care and living a normal 21st century life.

2. Stop sending credit card account requests to my dead mother. It’s been 7 years, she is not looking for a higher credit limit at the moment, and it just frustrates my dad. She stopped voting over 8 years ago, and maybe that should matter in who gets the credit opportunities from the bank. I’d raise a request about junk calls too, but the people who set up the companies that make junk calls probably died years ago and it is all AI now. RIP MJ.

That’s all for now, just wanted to share some pleasant thoughts to the 3 people who still read this space. I am doing fine, have refilled my prescriptions with my doctor in one of the two states I go to while preparing for alternate care if I’m not in the first state I live in as much in 2025. In other words, still vertical when I shouldn’t be, and reacting to a song on repeat with great lines about college earning “the big D” and “would you like us to assign someone to worry your mother?”. I should be horizontal now.

Status Update from Party Leader

I'm off to do science and I'm still alive.

Since people keep asking, I’m doing fine. We’re planning for a change near the top, but for now some rest and relaxation. Tomorrow is the start of the Thirteen Days of Tango.

Epilogue: The I Me Mine Problem

The “Twelve Days of Sudoku” used our regular editorial and testing team and thanks go to them for continued support. Video additions to several of these posts are expected in the future but not this month.

Ready Layer One” and all associated content were a production by one person and all credit/blame belongs to me for the unusual experience. While a solo work, this does not mean there isn’t a long list of people to thank for ideas and love throughout the years that inspired a lot of the connections. To everyone who ever mattered in my life, and to everyone who still might, these puzzles, jokes, and other ideas are for you from deep inside my brain. The stories you share back are the return gift to sender that I’ll await through the years when the layers finally get cracked open.

Some posts still need minor edits or addition of offline content once people verify passwords, but nothing new should appear for starting explorers for awhile. For future visitors, the best trailheads are still the two links above. Other items add into the series, such as the Motivational Posters as puzzlehunt style challenges for “Twelve Days” followers, and the story/flavor text posts add to the experience but are not starting points. All posts tagged “Puzzle” have something I expect a person could discover and might want to “submit” if they figure out what and how.

Besides puzzles and favorite books and music and science history and other things, this very personal series does include aspects of mental illness/wellness, including the stigma associated with it and not being able to convince people you are ok after they’ve seen you can sometimes be ill. These are all things I have been coming to terms with in being bipolar over the last few years after several hospitalizations and large changes in professional work life. In the altered words of Brave New World, I’m claiming the right to be manic and depressed, just not most of the time. I do not want medication that would prevent me from having the kind of brain I have. My bursts of creativity do change with my mood, even when just slightly heightened, as does my willingness to be introspective and grow by sharing thoughts. A healthy Thomas balances mood but has some ups and downs within identified bounds. That said, my rate of typing and pace of thoughts even on normal days can seem overwhelming to people observing the process. This was the first series where, despite the required content being made before anything went live, the extra touches added in the downswing phase of a short creative period revealed the artist at work and frightened several people (at least based on my ability to read into comments, discord posts, etc.). It almost certainly kept many people from going down the rabbitholes for fear they would lead to nowhere, when they always were intended to lead to 3 “first round” puzzles/stories that followed the beginnings seen here.

Be sure that if I am somewhere near “we” on the mental __llness chart below, as I am today as the series “ends” its launch phase, it is mainly because of our shared memories of community together, fun memories that cross boundaries of space and time. I do think societal impacts from COVID-19 and having to lay off some team members in my science job led directly to my first severe bipolar episode, as my community of we became a party of one. WE -> I = illness. I’ve been trying to build back friendships where geography is far apart ever since, and this series is a gift to those friends that made me feel happy before and will again. Even having someone just recognize a photo as my Hovse’s cannon and sharing a memory of recovering it from Mudd made my day, so even weak (but close) connections should reach out if they find something for them.

Soundtrack: 4th album by 💀🚕🇶🇶🇶🇶☕, and other purposefully random playlists that spin out from there.

Demotivational Poster (1 of many): A Mine is a Terrible Thing to Waste…

Now that we’re approaching the end of the Twelve Days of Sudoku, I’m sure everyone is curious what went on / is going on / will go on with these puzzles. If I had not stopped blogging my thoughts (when I ended my livejournal) and continued thoughts + puzzles, would this amount of raw Snyder have felt less overwhelming? I consider the collected works in these last two weeks my best stuff in puzzles+creativity over the last decade, even if that required exposing more personal things in the making and doing that not everyone in the audience is ready to talk about yet.

For today’s extra post, we start with just a sketch of a fully completed but very weird puzzle idea like the Christmas Miracle I’d posted before the trip. I made this on the flights back to seeing my father in my childhood home, when watching Little Women on the in-flight screen was a bit too boring although something I knew I was supposed to do. If looking for places to start that should get you going with this puzzle series, consider standard puzzles, notes documents, motivational things. Ready Layer One on its own has two answers and with other content at least one more. No one has found any of those. For sure, do not start with this demotivational poster. At least until I digitize it properly. Even then, here is a Knowledge Bomb squared: You aren’t ready for it.
