I am currently teaching a course on Creativity in Teaching & Learning and as a part of that I was searching for an interesting image to highlight a note I was posting to the class. I wanted an image that represented, in some cool manner, the multi-dimensionality of perception, how the “position” we take, defines what we see. Not satisfied with what I was coming up with (via Google or Flickr) I started doodling and pretty soon I had a new triplet ambigram.
Triplet ambigrams are 3-d shapes that cast different shadows depending on where you shine light on it. Now every shape (or most shapes) cast different shadows when light falls on them from different direction – the issue is to make these shadows interesting. In the case of triplet ambigrams, the challenge is constructing the simplest object that can make interesting and different shadows.
Here is what I came up with. This three-d shape casts three different shadows – each of which is a letter-form, in this case the letters A, B & C. How cool is that.

I also took a picture of my doodles as I came up with this shape. Here is a small version of that sketch (a larger version is available on Flickr).

I have created a few more of these things before. Here is one for CFT (Cognitive Flexibility Theory). I had posted this triplet earlier in the context of the periodic table of elements here.
And another for Cognitive Technology Society. This logo was selected for use by the organization and then they changed their mind, or the organization vanished (one or the other).
