Write a fully machine vision aimbot for CSGO. Perhaps you could feed the mouse and keyboard input into the tracking algorithm to improve accuracy. You need to intercept the mouse input anyway to tamper with the game state.

Predict a coin flip realtime.

Write a program that retroactively looks for a certain cat in a security cam footage (I miss my cat). This is the one I actually attempted a while ago using a the most dumb method known to man: Since it was an orange cat on a mostly grey/green footage I just defined a color range from dark brownish orange to light brownish orange and parsed each frame of the recording. It didn't work that well without defining a lot of treshold rules.

There are quite a few deterministic carnival/arcade games you could cheat with a bit of machine vision magic :^) Stacker comes to mind for example
