Perhaps this could be better answered on Stack Overflow, but I thought it would be worth posting here. Right now I'm trying to make visual transitions with pygame's surfarray module which uses NumPy. I'm using Cave Story's dimonddiamond-checkerboard transitions as a model right now (you can see them in this video http://www.youtube.com/watch?v=mJbAs-sSX4A).
I'm new to NumPy and I'm a little bit over my head. Is there an easy way to accomplish this, or are there any tutorials I should be following? Google brought up a bunch of general NumPy tutorials which I didn't find very helpful for my specific needs.
