We know that an icosahedron is a polyhedron with 20 equilateral 
triangles as faces. We need to know what it looks like. Do you know 
where we can find a picture? This is a summer enrichment project for 
students at Springfield Elementary School in Jobstown, N.J.

Here are a couple of good pictures:

Now for the good stuff!

This page is absolutely incredible!

If your Web browser supports VRML (Virtual Reality Modeling Language) 
then you're in for a real treat!  Because these images have so many 
sides, it's often hard to imagine what's on the back of the image.  If 
you can support VRML then you can bring up the images and actually 
rotate them about their central axis so you can see the back side.  I 
really hope you can do this because it is so cool.  Here's where to 
go:

Just click on any of the files and you're in business.  
If your Web browser shows a message that it does not know what to do 
with files of mime type x-world/x-vrml then read about how to set your 
web browser to view virtual reality files here:

I hope this information is helpful.
