In my first collaborative effort I'll be working with long time friend Chris Gartner who has just launched http://www.gartnergalleries.com/. We want to bring his photography work to the mobile space to use as Lock Scren images and Wallpapers. My first target is Windows Phone 7, but plan on trying my hand at iOS in the future as well.
Keep an eye out for a new page showcasing the app here on the site. And while you wait, head on over and check out his site.
