Huffman mobile
Interactions
- click a letter tile: one more of that letter is added, the tile grows, the mobile tilts out of balance, then it is taken apart and rebuilt as the new optimal tree
- drag a tile: the mobile swings and settles back to level by its own physics
- click the tapes: the decoder bead reads the short tape through the mobile again
- move the pointer: the mobile turns and sways in the draught
