Hello,
My name is Richard, I'm 21, I'm currently studying Graphic Design at uni, and I pixel in my spare time. I started pixelling in the pixel car movement, and have been pixelling odd things here and there since then. I think the pixel work I'm most proud of is the still life stuff, like the Polycarbonate Macbook:

And the iPhone 4:

I also enjoy pixelling cars, although unlike the cars I used to do I've switched to Isometric style, which I feel is more dynamic than a front, side and rear.

As a Mac user I currently use Photoshop CS3 in pencil mode, it's fiddly in places but the layers come in handy for keeping versions if I have to back up a few steps.
You can see more of my work over at

I'm currently busy with uni work, but I hope to be adding some work in progress pieces very soon!
