Sebastian currently works on a project called 'PROJECT ELECTRIC SHEEP' an AI/Story-driven dream simulator. Sounds odd? You better bet.
Beat Puncher and PIXEL.FOCKR have this 'Seb'-look - I call it so - and he worked at Deadelic Munich. So keep somewhat 2021 in mind.
Oh, Did I mentioned 'RobotRejects' on which I had the honour to work with this man? Now I did.

You are into shaders, hm? Alex of lexdev.net will help you to get started with DirectX.
