@Blue_Random has a much improved version here: https://scratch.mit.edu/projects/387204520/ The slider allows you to select the resolution. The greater the depth the clearer the picture - but also the more time it will take to scan. At the default setting it will look a lot like minecraft. You need a camera for this to work. It will provide a colour scan of whatever is seen through your camera. You will see black squares once it starts scanning.
