Droid Post Cards

[savagecreature]

So, I have this friend who ran across a pile of post cards he'd had lying around for ages and he decided to start sending them out. He writes a couple of short sentences, slaps a stamp on them and into the mail they go. He's calling them his analog twitter.  I've been lucky enough to receive two, so far.
Both times I thought, "I should send a post card back", but I didn't really want to go out and purchase just any ole post card. I wanted it to be something unique.  Last night I was messing around with some stuff and came up with this, the first in what may end up being a series of droid post cards:

 I printed one on my plotter, but the pressure setting was wrong, I think, 'cause it only drew half of it. But it still looked pretty cool. I'll give it another try today and post photos of the actual finished product when they turn out properly.
