Hypercube

My Son Writes:

Hey Mom.

This is the URL;

It starts out spinning automatically but you can stop it and move it by hand, too. To change the type of image (3-D glasses or stereogram) you click the "stereo" button.

Might get a headache though... so be careful.

Love,

I like the stereogram best.

To see it in 3D look past the image until the two images merge.
