Playing with javascript: ASCII 3d model viewer

I found very interesting websites that use javascript in a unusual way. Normally, javascript is known as a primitive script language with slow performance. But it can at least do the same as real programming languages.

The first one inspired me to use it for every possible 3d model and not only the given one. The simplest possible 3d file format is wavefront .obj, so I added an importer, made a user interface and viewed some of my models.

Try it out: ASCII 3D Art Note: This takes much of your computers performance, so use only simple triangulated models with less than 200 faces. (Don't use Internet Explorer, which is not able to support web standards)
