And now it occurs to me that this is a good way to illustrate the concept of a locus...after all, this is the locus of my finger!
Anyone can try to draw the locus too. Just do this:
- click "comment" (you may be asked to join voicethread - all they want is an email and username so they can assign you an avatar)
- click "record"
- click one of the pretty palette colours
- click the play button (lower left hand corner of video window - only appears when you move your mouse there)
- try to follow my finger with your mouse!
- click "save" if you're happy with it, or "cancel" if you're not
