I have a few links for Bunny. The first is an alternative piano keyboard layout [1] (link via Microclesia [2]) that to me, would seem to make piano playing easier, as each scale is played in an identical manner, instead of having to learn a dozen different fingerings.
The second one is this unique musical visualization of jazz music [3] (link also via Microclesia [4]). I personally have a hard time “hearing” music when looking at its printed representation, so I find these visualizations helping in “seeing” music.
It's actually quite amusing—I saved a link to the laptop orchestra [5] that my dad sent me over four years ago (yes, I have quite the backlog) that now, I just don't find all that interesting (and I don't think Bunny would find interesting either) but the following posts from that blog I found extremely interesting.
