There was a plugin competition and a Sandbox styling competition recently.
Sandbox is a theme for WordPress that you can make or get custom skins for. The skins adapt to however many sidebars you pick in Sandbox, so that’s cool. Loads of beautiful themes were entered.
For plugins, I snagged a few cool ones to test on my own blog here. I’m doing that now, so in case anything goes funky, that’s why.
