Proposed UI: a left mouse click with no drag creates a default (or random?) size, while clicking and dragging allows you to set your own size. Consider also how extensively the click-and-drag interaction is used in Paint, Colors, Etoys, TurtleArt and Scratch. > Maybe we can present the kid > on right mouse click with a palette and let’s say 3 objects at different > sizes to select from?
