Start with the informal sketching interface that I went over in class, which is at http://mrl.nyu.edu/~perlin/drawing/. Play around with it, make yourself familiar with it. Then try to make some interesting addition to it, and post your version on-line. Suggestions that people made in the class include:

• 3D items
• Rotate items
• Scale items
• Ability to edit individual points
• Morphing
• Different sized images
• Grouping items together
• Pan/zoom the drawing surface
• Continuous color mixing
• Animate continuous drawing
• Split an item into parts
• Items with their own behavior
• Save/load to a web server
