And if you can't knit, you can now buy a knitted Klein bottle hat from Cliff
Stoll's company Acme Klein Bottle (http://www.kleinbottle.com/).
I recommend the entire Acme Klein Bottle site; it's hilarious. For example,
the Unconditional Guarantee includes this clause: "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." Note,
though, that this is a for-real company and will actually sell you a glass
Klein bottle.
