scagliola?

[Jean-Joseph Cote]

First, a hint: "scagliola" is a noun.  I mention this because nobody took
up Ranjit's challenge:  "i'll be impressed if anyone manages to make a
non-noun out of this!".  (Obviously, I couldn't reveal the nature of the
challenge any earlier.)  So, the question at hand is, of course, which
noun?  Send me your twosies and your onesies by... hmm, I'm away next
weekend, so get them in by 5 PM on Thursday, and I'll send the results
out Thursday night.
