I felt the urge to start designing a 2300AD starship. It's one of the first times I did a quick sketch on my IPAD, and I absolutely love it. What will I do with all my pens? Oh, who am I kidding, I'm still going to eat trees, but I will probably do most sketching on screen. I think the only downside is the weird feeling of drawing on glass, which seems a bit slippy-slidy.
