My xypawn game is a demonstration of machine learning based on the original hexapawn game created in the 1960s that used a simple mechanical "computer" using only matchboxes and beads.
Hexapawn was a 3x3 chess-like board with 6 ("hexa-") pawns. My xypawn extends from there to be x by y dimensions.
I am trying to have the computer generalize its knowledge of previous experiences to extend to similar situations, including other board sizes.
At this point, you can play full games against the computer in a variety of board sizes. All previous moves are shown in small diagrams below the board. The diagrams also indicate all the alternative moves the computer had to consider. I am still working on the A.I. aspect of the computer's choices.work in progress
I've always been into coin collecting. Now I've taken it to another level by taking high-resolution (professional quality?) photographs of coins. See some of my best photos and zoom until you see every imperfection - of the coins, not the photos.
I also have some visualizations of the history of US coin mintage. It's surprising (to me at least) how disparate the mintage quantities were from the beginning of the 20th century to the end. It's also surprising how inconsistently some denominations have been minted. OK, so the 20-cent coin was a failed experiment, but the dollar coin? That would seem like the constant foundation behind it all, but no.
These are my favorite cars. They're not necessarily the best cars, or the fastest. This is all about the design - I just love the way they look. For that reason, I've included concept cars alongside production cars.
