Photoshop :: Gel Thingy (space Slug)

When I had a pause, making my new site I made something strange in photoshop.

This is what I did(You can find it under tutorials on my site):
"Create a new picture, 400 x 400 pixels, CMYK colour. Fill it with a medium blue colour. Then create a new layer and use the airbrush tool, size 65 pixels to create some red lines on the edges of the picture. You do not have to be very accurat on this... The red colour will be the aura around the gel. Another cool effect is to use the same blue as the background.

Run Gaussian blur with a radius of about 100 pixels, and set the layer to colour dodge. Choose Airbrush again, and set the size to 200 pixels. Drag it diagonally across the picture and you will have the gel effect."
