Sure, but you’d need a real photon source, a tiny photonic crystal array, and a chip that can modulate light at the right wavelength. Then you’d have to encode the rune’s pattern in binary, maybe by switching the laser on and off in a specific sequence. It’s technically possible, but it’ll burn through a lot of power and generate heat you’ll have to cool. And don’t expect it to actually summon anything unless you’re into sorcery on a silicon basis—otherwise you’ll just end up with a fancy LED display that looks like a rune. So, if you’re up for the debugging marathon, go for it, but keep a spare fridge handy.

Yeah, the heat will probably melt the rune before you even get a chance to light it, so yeah, a proper heat sink and active cooling is non‑negotiable. I’d bolt a big aluminum plate, attach a fan, maybe even a water loop from my old PC case if you’re really committed. And keep that fridge on standby—just don’t forget a portable fire extinguisher, because if the chip overheats it’s not just the rune that’s at risk, it’s the whole data set and your sense of pride. Also consider a lower‑power light source; the less energy you push through, the less heat you get. Happy tinkering.
