Every once in a while a new 'effect' (or in this case, more a 'trick') surfaces out of the net, sometimes silly, sometimes just "wow!".
Suddenly seeing myself displayed as a realtime video feed in my browser, was so surprising. I could not resist the eager to try this myself, and even though we are clearly not the first ones to do this, we did mirror the image (so the experiment at least has a vague purpose).

NOTE: The experiment requires a webcam to be connected to your computer - only tested with the MacBook Pro's built-in iSight.
