Cool,
It was a neat idea, but I can't see there being much of a market so to speak for this kind of thing. When the Etch a sketch was made, it was made to make car trips less boring, and to keep kids entertained (distracted) for a little while. This, although fairly well done, especially for your first flash, doesn't have the same feel or entertainment value as the real thing. It just seems to be lacking something that the original had, perhaps the controls are just too simple on this one, or there isnt any pressure if you screw up. I dono, good idea, but it probably won't pass with flying colors, but don't worry about it, you can't expect your first try to be great, so get back up and dust yourself off, and start making more!
