I love how simplistic these icons are, yet also how fresh. These are all icons of things I've seen before, but they look interesting in your style. They seem to have just a little depth to them from the gradient to make them cute. Thank you for sharing!
This reminds me of Pictos: [link] In short, the Pictos font is like a webdings font, but with pictures that are actually useful for web and device. I imagine the same thing can be done with the icons you've done here =]
