Here's a small demo we made for Flashback 2019 held in Sydney. There are some firsts (I think... I hope) like the full screen X/Y distorter (at 60 FPS).

P.S. I used my very old code that seem to use someone's matrix math functions and I can't find the thread I borrowed them from so thanks and credits to him/her! They're named like rot_x_m() and lookat_m() etc.
