Drawing simple and not interactive pictures with Processing was a great way to start. Then adding animations and interaction were the next steps. I really enjoyed creating kind of art with code. In some cases the results were really nice. Drawing with code is very easy for someone who knows how to do it but since I didn’t have any previous experience I was many times mesmerised by the power of if and of course by the results, too.
As a final project I created an Asteroids type of shooting game. I wanted to see and learn how a simple game engine can be created. I was quite happy with the result. You can play the game here: http://tuomasahva.net/bubblexploder/bubblexploder.html
