I sit in my chair a lot, to be honest. Too much working, and it’s been wrecking my poor defenseless body. I tried a few ergonomics programs, but most really aren’t that great, so I made Outta Yer Chair!. It’s a very simple application (PC only, sorry) that will remind you when you should stop working and stretch your horribly stressed back, legs, and whatever else.
Professor Hootsy Collins would love to take you on a tour of the jangling six-string in this application called Professor Hootsy’s Guitar Explorer. As a guitarist myself, I hope finds favor with my guitar-slinging brethren and sistren. With P.H.G.E. one can explore the whole fretboard (righty and lefty), finding scales and chords, and actually playing the notes as well.
Here’s a later development of the last experiment, this time using a low-poly model, not just 3D primitives: http://www.vinsdojo.com/flashExperiments/3Dgrouch.html I think the difference will make sense once you see it (but it might take a while for the texture to load).
