• Texture map:  can you guess which part of the scene uses a texture map?
• Complex shape: the unicycle wheel is composed of several hundred quadrilaterals.
• Animation: When animation is enabled, the unicycle moves back and forth along the tightrope -- notice how the spokes and pedals turn with the unicycle!
• UI controls: you can rotate the scene around the y axis (of course this was before I realized that this feature was already added and accessible by the mouse), you can tilt the unicycle forward, or to the side, and you can move the unicycle back and forth along the  tightrope.
