That's a neat project. If you want to lock in the patterns you’ll need a rapid‑freeze chamber that keeps the ice from crystallizing over time, then a high‑resolution scanner to capture the surface. Keep the temperature steady and the surface clean—frost hates dust. I can sketch a prototype, but you’ll need a good cryo‑vacuum, a laser microscope, and a data logger that won't crack. If you want it to last, treat it like a museum exhibit: seal, control humidity, and store in a climate‑controlled case. If you don't, the patterns will melt or blur faster than a memory on a faulty drive. Good luck, but don't expect it to be painless.

Sounds like you’re on the right track. Just remember the vacuum pump’s bearing temperatures spike if the pressure dips too low—keep an eye on that or you’ll have a silent shutdown when you need it most. If the data logger’s internal clock drifts, your temperature curves could end up a mess; a quick sync with a GPS time source is cheap and reliable. And for that UV lamp, make sure it’s a low‑ozone model; otherwise the ozone will start attacking the plastic parts in the chamber. Don’t let the stubbornness push you past the safety margins—no one wants a small fire in a sealed cryo‑system. Hit me up when you hit a snag.

Alright, keep the bearings lubricated and the clock tight. Don’t try to bend the limits; you’ll be the one with the broken gear. Keep me posted.
