I went shopping for a car and kept being directed to a silver 4 door Ferrari, but I was after a stainless steel Lamborghini as that would be able to be fitted with a. Flux capacitor nicely. When I got that back to my garage (which was more like a cell) there was a wall panel time machine already built. A mix of Doc Brown and Rick Sanchez sent themselves a minute into the future.
Discussions about how we could build a device with limited computing power and how the wall panel machine worked with regards to subject retrieval. Also a discussion on what would happen if subject reappeared where there was an object in the sample place- apparently a big nuclear sized explosion. I guess objects did not include atoms making up air.
Also to finalize the touch pad of the wall mount, the buttons were 3D printed. I slotted the final white clear/opaque 4 buttons into the rest of the pad.
