Blender's really come on since I last looked at it a year ago, so I'm trying to get to know it. Thought I'd try a really quick and dirty storyboard/previz thing - wrote a quick tune in Logic (yay harmonica yay) and then tried to illustrate it as fast as possible in Blender. Nothing's textured, and the excessive lens flares are there out of necessity, hiding a multitude of sins... (though nothing can forgive the nasty hard edge on the nebula photo, d'oh, no time to re-render)
