Marvel craft: DIY LED Tesseract
Did you know that in geometry, a tesseract, also called an 8-cell or regular octachoron or cubic prism, is the four-dimensional analog of the cube? According to Wolfram MathWorld, in Madeleine L’Engle’s novel, A Wrinkle in Time, the characters in the story travel through time and space using tesseracts. According to Google, Tesseract is also probably the most accurate open source OCR engine available.
Of course, in the Marvel universe, there is yet another use of a Tesseract – as an Infinity Stone, one of the most powerful artifacts in the universe. It can open rifts in space, which ties in nicely with Madeleine L’Engle’s use of it. While Odin keeps watch over the Tesseract in Asgard, you can create your own replica based on this quick project by Venessa Baez (complete with 3-1/2 minute video). With an acrylic photo cube, a few swipes of paint, some LED garden lights, and waxed paper, you can have a great geeky decor item for your desk or bookshelf.
If you could open a rift in time and space, where would you go? And would you make the “Vwoop, vwoop!” sound effect like a TARDIS?

So, this week’s Friday Round-Up celebrates one of my heroes, Darwin. The well-known two legged take on the ichthys symbol is used by fans of evolution (can a scientific theory have fans? Does it matter if it does or not? It’s popularity’s kinda irrelevant; it’s still true…). Darwin Fish (Or Tonys, as all good Feeters know) are rough depictions of Ichyostega, the remains of which are important transitional fossils between tetrapods and fish, since they have a tail and gulls akin to fish but amphibian style skull and limbs.
