The Droste Effect is the motif of an image wholly containing itself (and so on, forever). Here we see an animated example of this effect featuring David Hasselhoff modeling his custom Speedos which are printed with the alluring image of…David Hasselhoff wearing Speedos.

Another sort of similar animation but much creepier, also from Geriatric Punks.

Here is the original Droste hot chocolate box for which the effect is named, no doubt responsible for wrecking many a young Dutch head. This is probably what got that Escher going. Speaking of which, here are some Drostian animations of Escher images for your edification. I can’t seem to find an actual animation of the Droste box, though I have seen one somewhere.

While I’m on the subject, though it is probably pretty old hat by now, if you haven’t you should probably take a look at the zoomquilt.

Oh my! Just looked at the top level of where that Droste image was hosted, and it was a site devoted to images of cats looking at computer monitors with images of cats looking at other cats on computer monitors.
