As we studied light, optics, and human vision, we discussed a relatively simple way to make your own red cyan anaglyphs at home. A little searching online easily brings up many guides on how to do this process. The following guide is a good one, since it is thorough and requires only freely available software. The image editor it uses is a free alternative to Photoshop called
gimp (the GNU Image Manipulation Program). Many other alternate programs (including Photoshop itself) can be substituted.
The guide can be found here:

Have fun, be creative, and let's make some cool 3D images to share!
