Hey, this sounds totally cool! But I'm already running a robot side challenge in March so probably won't have time to post too much. I'll definitely check in though!
Change up the background by using different coloured mat board over top of your creation. Place it right on top or just hold it, swirl it or whatever over the top while the scan is happening.
I had this thread on "Watch" because I wanted to get a glimpse of the images displayed here. I'm already in an intensive March side-Challenge and my ancient CanoScanner is buried under equipment and a box of Kleenex. The stuff I moved off came in contact with the keyboard (hey, my space is not finite) and a few things didn't work for a while. Yeah, well, anyhow. This topic, Scanner Art, is really interesting and fun. So, can I have "in" please?
One thing you might note, is that scanner plattern glass tends to be rather soft and very easy to scratch. Even carefully putting nuts, bolts, rocks, stones and etc on the glass can scratch it... forwarned is fore-armed. I recently had to replace the plattern of my large format expensive graphics scanner because I put many tiny scratches on it.... I was tired of spending hours cloning the scratches out! :)
