Thank you so much for the feedback! That sounds like a really cool stand and I'm glad you had so much fun developing it! (I'd love to see what it looks like once you get the appearance down. If you don't mind, that is.)
About the ability to save the image: I tried to add that during development but I'm still a relative beginner at programming and I couldn't get it to work right so I had to abandon that feature (for now, at least, I might give it another go). Instead I've been using a free application called Gayazo that works pretty well to screenshot whatever you want. If you would rather not download anything, you can hit the "PrtSc" button to copy a screenshot to your clipboard and then paste it into an application like Gimp or Office Word. Hope this helps!
