mieko's rbclutter-unofficial at clutter-1.4 - GitHub
Since the move to Clutter, I’ve been randomly patching rbclutter to support 1.2+ features. Thanks to bpeel for rbclutter to begin with, and with some advice on my (slow) quest to get it up to speed with Clutter proper.
There are still some minor hacks in there from my days of “just get it working” (implementing dup instead of initialize_copy, reusing VALUES without much care to the GObject refct, etc), but it mostly works, and has support for a few newer things that I’ve needed.
