WE are going to make a pixelated gel effect similar to this:

1. First, make a new file, 500x500
2. hit d to reset the colors, and go to Filter>Render>Clouds and duplicate the layer
3. On layer 2, Filter>Render>Difference clouds
4. Make a new layer and get out the gradient
5. Set the mode to difference and everything else at default.
6. Go crazy, until you get something like this:

7. Then, set the top layer mode to overlay, set the second layer mode to overlay.
8. Make them a combination of any colors you want using Ctrl + U, then hit Ctrl + Shift + A for autolevels.
9. Merge them all together then go to liquify and go crazy
10. Make a border around your document, preferably 5 or 10 pixels.
11. Select inverse, then go to Filter>Pixelate>Mosiac and switch to 1
And your done!
