This Sand
This generator was very simple. All you had to do was click and hold and it would create little sand pyramids. Although, you could select any color. You could also hold down and mix the colors so the pyramids would fade to different colors. When I used it the first time I didn't understand the colors at first. The second time I used it I created several color gradient pyramids. They turned out very cool.
Neave Imagination
This generator was similar to the last. It wasn't drawing, it was more of a guided art. All you had to do was drag your mouse across the screen and it made a form of light design. If you held down the clicker is would light up the line more and the design would fade. However, I found this generator somewhat pointless.
Viscosity
This generator started with an image and you could obstruct the image. You could change the color set or use grayscale or one of the given ones. It was a geometric image. You had to use the different tools offered to change the image. I enjoyed this generator. However, it was a little hard to navigate and I still do not totally understand it.
