Luckily, it's easier to build than to pronounce. First, eat a lollipop! Huh?
So the big question is, what is a Phenakistoscope and is it going to hurt me? I found some good information from Wikipedia:
The phenakistoscope (also spelled phenakistiscope) was an early animation device, the predecessor of the zoetrope. It was invented in 1831 simultaneously by the Belgian Joseph Plateau and the Austrian Simon von Stampfer. The word "phenakistoscope" comes from Greek roots meaning "to cheat", as it deceives the eye by making the pictures look like an animation.
And no, it isn’t going to hurt you! Not even in the wallet! Best of all, it takes about 15 – 20 minutes to build. Let’s get started.
