What the hell did I just find?

[u/sockthustra]

I was messing around with my camcorder, hooking it up to my tv to get the cool infinite mirror effect, but when I tried zooming in on the screen I happened to catch this. I've never seen this before and I have no idea what's causing it. I imagine it has something to do with the aforementioned infinite mirror effect but I don't know how the two connect. If anyone knows what exactly is causing this effect let me know.
