UFO, or Olive?

UFO, or Olive?,

Played hookie from the last CE session today; my presentation will be tomorrow morning, then it's onto the Big Bird again and home. So this evening is the only time available (well, was the only time available) for photography. Made several more than this, so more coming. But tonight, practice for tomorrow morning.

So, is it a UFO, or what?
