monkeysign <http://web.monkeysphere.info/monkeysign/> also exists.

Unfortunately, it seems monkeysign generates a bare QR code (containing
the fingerprint, or at least, it doesn't look information-rich enough
for a whole key to me). I agree it'd be better if it produced a
gpg-key2ps-style keyslip, with the QR code added at one end: then you
could show the QR code to your webcam as a shortcut for data-entry, and
check the on-screen fingerprint and details against the ones on the slip
(the same way you would if you'd retrieved a key by its short key ID).
