William Hundley photographs ghosts... or something. The 'or something' apparently being his friends jumping in bed sheets. This looks like a fun photography/Photoshop project to try out. I doubt it is quite as easy as it sounds (unless your friends are professional canonballers, cheerleaders, or just plain fabulous jumpers). I just like the idea that ghosts where bedsheets, especially in broad daylight. Check out the rest of William Hundley's Entoptic Phenomena series here. (Found through Photojojo).
