Challenge: Build the smallest transformer that can add two 10-digit numbers with = 99% accuracy on a held-out 10K test set.
ballin#One night — after a glass of wine — I had another idea: one modern trick with ASCII art is the use of Braille unicode characters to allow for very high detail. That reminded me of ball physics simulations, so what about building a full physics simulator also in the terminal? So I asked Opus 4.5 to create a terminal physics simulator with the rapier 2D physics engine and a detailed explanation of the Braille character trick: this time Opus did better and completed it in one-shot, so I spent more time making it colorful and fun. I pessimistically thought the engine would only be able to handle a few hundred balls: instead, the Rust codebase can handle over 10,000 logical balls!
