I needed a bit of a break from all things gamey this evening, so I looked back over my old plasma source.

By stripping the maths down to the bare minimum and using a for...each loop along with other bits and bobs ( Double buffering the screen helped too ) I managed to increase the fps from the 31/32 mark to 42/43.
Pretty sweet.

I thought I could either post it like that, smug in the knowledge that I've speeded up a pretty intensive routine by ( In real terms ) quite a lot, or do something slightly different.

I opted for a bit of a play, and was really surprised ( And pleased ) to see you can attach the same bitmap to multiple sprites and it still updates. From there it was a no brainer what to do with it. In real terms this is plotting less pixels than the plasma effect ( That was 150x150 doubled ), this is a 120x120, but it's a much bigger effect in terms of screen size.
