On the jsxGraph blog, there is a video showing a construction being manipulated by touch on the iPhone – very cool.
Experimenting with their circles-on-circles web app, by sliding the parameters around I uncovered this delightful piece, which reminded me of those ornate calligraphy end-notes you see in olde books.
Its a lot of fun to experiment. For the curious, the parameters of this specimen are : c1:0.51 f1:7 c2:0.32 f2:17
I think SVG is the right way to go, and a more natural approach than using canvas [as I did for my interactive sine generator last week].
There’s no technical reason now why something as featured as GeoGebra or KGeo could not be implemented directly in the browser.. it just has to be done!
Geogebra is really nice, but I do prefer the simplicity of not having to download the java applet and approve it for access. Each extra step supposedly halves the audience, and I want math to be interactive and accessible.
