Interested in mathematical origami or Swedish folk music?  How about online education or filmmaking?  If so, you might want to take a look at the project I'm working on, a site at gardenedu.org.  It's a page of video-lessons organized in 2 trees of subject matters: "Swedish Folk Music" and "Origami Design."

First of all, I hope you just think it's pretty.  I had a lot of fun doing the art - and the visual metaphore is that 'topics' are trees suspending glowing spheres: 'concepts' so to speak.  I'm not enough of an artist to fully demonstrate how beautiful this idea looks to me:  a forrest, (perhaps more like a garden for the variety ;-) full of softly glowing spheres connected by strings of smaller lights, like a neural network of lights draped over a living forrest.  If I could, I'd make a video in which you zoom out now and see that this lit forrest is itself inside a glowing sphere with thin lines connecting it to nearby concepts in aesthetics, education, and engineering:

So, in that order:

And more feedback/recomendations/insights on what's up already would, of
course, be appreciated!  So comment or email me if you have ideas! :)
