Speaking of Christian-ish horrors, some of the biblical descriptions of angels are pretty lovecraftian. Bodies of intersecting wheels covered in eyes, for example.
For some reason, whenever I hear that, and the burning bush and such (floating balls of light and etc.), I always looked at it like fractals in meatspace (or extra-dimensional computer programs, somewhat Matrix-like raw data entities; in some cases, virus-scanners that keep the universe in check (they don't all need to be Agent Smith/MIB).). Then again, I've watched
Electric Sheep quite a bit; but you can describe that screensaver pretty much the same way in most cases. In other words, angels and such could just be floating math (will-o-wisps of data/programs/files/etc. Sorta like Tron, but non-humanoid in nature/form.).
O = Neutral, <> = Yes, >< = No
Also, why else would certain avatars change from looking something like Electric Sheep or whatnot into something less mind-breaking like another human being or a talking platypus? Or at least, introduce themselves with "fear not.", while in their raw forms?
EDIT:
Right, that wheels in wheels thing also works with my UFO post earlier. UFOs don't necessarily need to be vehicles. Some of those could be a portion or the full-actual body of an entity. Kinda like talking to a rock or machine component. And for some reason, Master of Orion and Starcon come to mind (from Silicoids, Taalo, and Chenjesu (sentient rocks, though Chenjesu are more like sentient crystals)) to Mmrnmhrm and Meklar (sentient machines), and the Chmmr (a hybrid of both Chenjesu and Mmrnmhrm; rock-machine/mechanical rocks)).
