Create a high-tech, abstract design from scratch.

1. Start off by creating a new, 800-by-600-pixel canvas in Photoshop. Fill the background layer with black.

2. Use the Elliptical Marquee tool to draw a circle in the center of the canvas (on the background layer). Press D to set your foreground and background colors to the defaults, and then choose Filter > Render > Clouds. Deselect, and you should have something like my example. Alternatively, why not experiment with your own shapes?

3. Now choose Filter > Stylize > Extrude. Choose Pyramids as the Type, 30 pixels in Size and with a Depth setting of 255, Random. Or try your own settings in the Extrude dialog box. This filter, with my settings, will give you a three-dimensional, spiky-looking object.

4. Color the object by choosing Image > Adjustments > Hue/Saturation. You can give it an orange color like mine, or experiment and choose your own. Be sure the Colorize box is checked.
