Maths and Graphs

I often had a problem where I wanted something to look normal when the mousecursor was in the center of the stage, but had to look different when pointing to the left and/or right.

I remembered a formula at mathclass in which you could get a parabola graph, which was which I needed basically.

I also wanted to test out how to implement glow and blur filters which needed to change dynamically. My first attempts naturally caused Flash to crash. When you create a new filter every frame Flash kinda does that. When I finally came up with a solution I was amazed how smooth it suddenly ran. Ever since I've been interested with performance tuning.
