Everyone in your neighbourhood is going to have a pumpkin carved with a goofy face sitting on their porches. Booooring. If you want to decorate for Halloween with something a little more original, why not turn your jack-o'-lantern into a working animated zoetrope and really wow all the kids stopping by to beg for free candy.
All you need to create your own zoetrope is basic pumpkin carving skills, access to a strobe light, and a spinning turntable. It will take a bit of fidgeting to get the turntable and strobe synced, but the results are totally worth the effort if it means the local kids will be too mesmerised to smash it.
