Ghost Frame Shows People (and Cats) That Don’t Exist

[Dan]’s project from last year slipped past us until now, but his Ghost Frame is a great example of tying some modern hackable hardware together with online resources into a clean result, and we like the clear idea behind it. The Ghost Frame is so named because its purpose is literally to show pictures of people (and cats) that do not exist in the physical world.

This cat does not exist (thank goodness.) The computer doesn’t always get it right.

To make it all work, [Dan] used an Adafruit PyPortal as the guts of the device. It pulls images from (which displays computer-assembled images of faces that do not represent actual living people) and displays them as though they were pictures in a digital photo frame. Formatting the image to show up nicely on the PyPortal’s 320 x 240 display took a little extra work; [Dan] solved that problem with a small PHP script to convert the image to a bitmap and scale it correctly in the process. The PyPortal makes fetching resources from the web simple, so this kind of fiddling didn’t present much of an obstacle to [Dan]’s artistic vision.

What about the cats? Well, it turns out that is also out there, and Ghost Frame can happily display computer-generated images of nonexistent cats as easily as it shows imaginary people. However, it does seem that the state of nonexistent cat generation is lagging somewhat behind that for people. The site usually gets it right, but results are occasionally (amusingly) bizarre as you can see here.

The PyPortal is perfect for this kind of project, and it can do more than just display static content. It has some GUI functionality baked in, as we saw showcased recently in this touchscreen Blackjack game.
