Today, Boing Boing linked to a post, A Four Dimensional Tribute to the Late Madeleine L’Engle, at The Bryant Park Project. Watching the Bryant Park’s excellent video I was reminded of the portion of Cosmos, seen below, where Carl does his best to explain the tesseract. Video after the fold.
Computer animated tesseract.
And another.
And a final other.
All apologies on the bad music.
