Lapo Calamandrei created a sample of Tango-ified new-style Human icons. They’re not remarkably different in style, just interpretation. Plus, they fit nicely with the rest of the Tango base theme. Very tasty! New-style Human on the left, Tango-ified versions on the right.
Update: I’ve coined a new name for the new-style Human icon theme… It’s Numan! Of course, it’ll still appear as Human when it ships.
