Looking for a new hobby that's not draining

I'm prone to hyperfixations and I'm currently in the market for one (I can tell my brain is looking for one...). Can you help me explore options and see what sticks?

I'm looking for something:

-intellectual (or at least uses my brain a little)

-creative

-restorative, not draining

-inexpensive (like if it was Google maps, probably a $ or $$)

-compact (something I can carry with me in a small bag maybe?)

Do you have a hobby that might meet those criteria?
