I use ThundeROM 1.5 and liked the animation of the opening and closing of the windows that was incorporated in the ROM (btw thank you beezy and KSmithInNY),but I stumbled on to this forum link at XDA Developers[UPDATED][UI Animations] New Android UI Animations - xda-developers and liked the option of changing them. The first method mentioned worked just fine. If anyone wants to try it out.
