My short term thing is this mathematical programming puzzel https://projecteuler.net/problem=160 from Project Euler where you need to calculate a very large factorial.
My live goal is to bring back more programming and design techniques that we as a society used to make the best ps1 and gameboy games and old school animations to the way we are currently developing games. (Any tips and advice how i could help improve the game development industry is welcome. Next year I will be doing my masters so i'm also still looking for a subject for that. The last couple of months I have been experimenting with water color effects in openGL, so I'm looking for something like that)
