The Friday Fillip

munkerwhite.gifA late and short fillip today — which got away from me (the day, I mean).

MIT is an endless source of fascination, most of which is available on the web. (I ask you: how many universities would let their students design the front page of their website — every single day??) Today I simply point you to the site of the Perceptual Science Group, which I kept reading as Perpetual Science Group, something else entirely.

Here you’ll find a music study that invites you to take part — do it, and tell them if this or that sound is sad or is best represented by an upward line or… — a motion and form tutorial, where, if you’re brighter than I am, and I know you are, you’ll learn a lot — and a bunch of those impossible illusions that are simply not true even when they are demonstrated to be… true (it’s the Munker-White illusion that annoys me no end: curse you, Munker, and you, too, White!).

Take a look. Take a listen. Munker-White.


  1. Yes, MIT examples are very good. A related field of study is that of ‘impossible figures’ (these are illusions too). Japanese are active in impossible figure research.
