The XAML Project

Seems there's a new boy in town to compete with The Noun Project and name is The XAML Project.

I've also discovered a new site called XAMALOT (luv the pun),

Metro Noun

Metro Noun is a project I have been working on just recently. It is a studio that lets you add SVG or XAML code and create custom Metro Icons. It can be used in to customise icons from the Noun Project in particular.

Here's a beta snap shot.
