FxGen

Makes use of the Lerp function. I did cheat a bit-- I exported this at 1024x1024 and shrunk it to 256x256 in my editor. It looks nicer that way. I probably could have done without that, however, and just stuck to the 256x256 default.

v 0.4a

UPDATE: Exported at 512x512, assembled at 1536x1536 in GIMP, then shrunk to 512x512 for upload.

PS-- Tiling: fixt :-)
ProTip: When attempting to tile textures such as this, it's all about Roto Zoom's rotation value.
