In the world of Spider-Man, Dr. Otto Octavius (better known as Doc Ock) has been augmented with a set of mechanical tentacles he uses for nefarious purposes. JLaservideo teamed up with a few internet friends to design and build a working tentacle backpack, and then gave it mind-control capabilities.
Inspired by the Jackie Chan movie The Spy Next Door, maker JLaservideo created a sword that stores like a belt. The tempered steel weapon works like a tape measure, bending around his waistline, then maintaining a semi-rigid shape when deployed. We’d be afraid of cutting ourselves pulling it out of its sheath.
