I don't know if this has been done before, but right now I am out of steam.
I can't think of anything else to do with it.
If you can give me some feedback or critique it I would really appreciate it.
Made a small edit, removed most of the final note, added a new experiment.
Anything else need work?
I'm still a bit concerned about how to imply what the wallet does without it being too obvious.
Changed the storage location, added two changes to the description, filled in the amounts of money from the experiment log.
I wonder what else needs to be done with it.
