In 1981, Steven L. Gibbs, a farmer from Clearwater, Nebraska, received an interesting message – from himself. This new Steven L. Gibbs was apparently from another dimension, and he had a diagram for a time machine called the Sonic Resonator, which he gave to our dimension’s Steven L. Gibbs. After building and testing the device, our Gibbs, who now lives in Lyndon, Kansas, improved upon the device and renamed it the Hyper Dimensional Resonator, which he began to sell as a time machine, astral projection generator, and healing device.
Despite the wackiness of the HDR backstory, strange things have been reported by people playing with Dimensional Resonators.
Also, buying the device is bizarrely difficult for something that seems so scammy. You’d expect a snake-oil salesman to be eager to take your money… but no. Steve Gibbs is apparently a dick.
