I wanted to make this image after seeing this render (http://bit.ly/Q0oEyL) by Nick Campbell. I wasn’t trying to fully recreate it but I thought it had a cool style and so I wanted to see if I could get that sort of effect in Blender. I rendered it in Cycles with just a simple Sun lamp and a Sky Background. I haven't been uploading my blends lately so this is actually kind of old, but that's ok. I put more info about it, like how I made it and stuff on my website, http://davidzerba.wordpress.com/2012/10/28/triangulated-mountains/.
Cool stuff here.
