Power of Two

I'm slowly starting to figure out how I can add graphics to the game. Basically I'm getting tired of the green, red and blue squares. So now I'll go for red, yellow(!) and green blinking circles instead.

I'll be working with sprite sheets for the animation. So far I've managed to get a clumsy animation running on the iPad by using a piece of java script I borrowed from the Unity community wiki. But I want to work in C# so now I have to rewrite it.

Oh and the "power of two"-title refers to the fact that in order to get nice graphics on the iPad I have to remember to use image sizes that are a power of two e.g. 256 x 1024.
