"Impossible" Escher-type parts

Remember the optical illusion of the three dimensional 'fork' with the
circular tops, basically rectilinear lower features that morph into
cylindrical upper features, but don't make sense. Seems like I remember
seeing a model of that somewhere.

Basically I'm looking for an interesting part for a business card and I
thought something along this vein might be suitable, any ideas?

Thanks

 

There is a good reason you used the word "Impossible".

And the reason is...

You may be able to create them using the stuff described on the following

It's mostly just perspective, see the next reply...

 

Cool thanks... still haven't found a good image of that fork thing though

 

You mean stuff like this?

You can do a "transmogrifier" with surfaces, but obviously not with
solids.

 

Actually, I take it back -- can't even do it with surfaces (the
"transmogrifier" is the fork-thingy).

 

Here you go - a simple version, but one nonetheless.

This is a classic case of why you want to be a CSWP and go to SWW. At
the last SWW they took the CSWPs for a special trip, part of which was
to drink a lot of beverages and the other was to view an exhibit of
impossible geometry while being within an example of impossible
geometry.
