Here's my second interactive sculpture!  It's had less time for the algae to grow on it, but so far I'm liking it.  With the snails piece, having them entirely underwater wasn't necessarily a "death sentence" for the snails as a number of species of snails are aquatic.  There are no aquatic pigeons, though, so I made this one to have its head jussssst above the top of the container.

I didn't take many in-process photos of this one primarily because a lot of pieces to this one were really delicate while uncured (the feet, the beak, the tail and wing tips) so I was mostly gently cradling it while sculpting and then went straight into curing it.  But to the right is a photo of it post-curing but pre-powdering.
