Klein bottles are cool.

The HMMT has given Klein bottles as awards for several years.

See: http://www.artofproblemsolving.com/Forum/album.php?mode=attach&id=7657

(See bottom center right.)

I think Acme is the source.

I love ACME's miscellaneous material that comes with the Klein bottles, like the "Care Instructions for your Manifold" or some such thing.

From their guarantee:
Quote:
We warrant each Acme Klein Bottle for a period of FIVE YEARS to be absolutely free of any magnetic monopoles. If you discover one, contact us immediately and we will refund your purchase price right after claiming the Nobel Prize.
