Got any tips on speed optimization? I know I should put my sine/cosines in a pregenerated array (or at least allocate enough memory at the beginning of the program to generate it all when the program starts) which would speed it up but I''m not exactly sure how to go about doing that in this particular instance. Btw this is a background for a tetris clone I''m working on, everyone''s gotta have one. (:
