I've recently gotten into 2D animation in Photoshop, then compiling the animations in Flash so I can add sound; these are for a game I'm making myself called Martian Democracy.

A HUGE help in animating these comes from a series of animation sheets my Flash teacher handed out to the class, giving multiple frames of various activities (running,hopping,skipping,sneaking,etc.). What I'm wondering is if anyone out there has something similar for isometric angles, basically reference sheets for drawing multiple frames of activity in an isometric perspective.
