Solfèd (draft - "solfire?")
Early version of Solfèd 2.0 http://scratch.mit.edu/projects/20832054/ - this is just an early draft, before the concept had evolved into feeding worms to birds. At this point, the birds are being shot with little red darts.
Basically, you just click numbers 1-7, based on the pitch "sung" by each new bird. Notes that you miss are grayed out. The later version linked above is much more fully developed.
