If you drink enough alcahol to get completely smashed (who isn't smashed 24/7, amiright?) and use the ornate spyglass (or presumably any item which gives longsight), then zoom out all the way, you will be able to see your own character. More importantly, your camera won't clip on walls, and so you can move your (editcamera through walls to see what is on the other side, or through the ground, etc. You will need to have your max camera distance turned all the way up.
I imagine this works due to the drunken effect of forcing your camera to zoom out further, combined with the spyglass only zooming in far enough to be incapable of seeing yourself.
I imagine there are a few useful things for you to find on the other side of walls, have fun.
