I have been wanting to try something for a while, but never really had the opportunity. It's called a Cinemagraph It's a moving Picture. You may laugh and go "Isn't that just a video you retard?"
to which I would respond with "NO YOU FOOL!"
Its basically a gif file, but it's a video that you 'freeze' everything in, except for a point of interest.
For example, (and i've only done one so far) I video'd a mates engine bay at the dyno comp today. With slight lighting changes, and a reflection in his polished alloy cover of someone walking past, i could freeze all that, and have just his cam gears spinning.
So here is the point that I present you with SHARPYS FIRST CINEMAGRAPH!
