There are buttons down on the bottom of the screen to look at the previous or next images. Keep in mind that the images are pretty low-res because of Scratch's limitations. Most of them are actually HD. I added in a different picture of the glass of water because it wasn't as grainy.
I made all these with an open source program called Blender: http://www.blender.org/ I got a lot of my Blender skills from this guy: http://www.blenderguru.com/ I edited the blue crystal picture with Gimp (http://www.gimp.org/) so it would look like an oil painting.
