After several copies of this original shape, go ahead and create a new and different shape with your polygonal lasso tool. Make sure to create a brand new layer and then choose a color to fill it with. Here I'm using a purple light blue color that has something to do with our global color theme.
If your selection is imperfect you can use the subtract from selection polygonal lasso tool to select the area that is imperfect and get rid of it from the selection (taught in full Photoshop CS video tutorials training program).
Drag this layer once you have filled it to the new layer icon and with the moVe tool, nudge it off again from the original layer. Ctrl click on the new layer icon to select with the army ants and then choose a lighter version of this color. Alt backspace or Edit: Fill to fill the selection with this color.
Now do your Ctrl E after linking these two layers to merge them together.
Keep doing a bunch of 3-D style transforming with your free transform and Ctrl/Cmd key. Yes you can do some pretty impressive 3-D effects within Photoshop...even though it is the 2-D worldwide image editing standard. Duplicate again and try another slightly different angle and place it where you think it should be.
Notice that I'm creating these in the general same direction. Yes, this is actually the first time I'm creating one of these designs (I don't believe it myself). A lot of these techniques I got from PhotoshopWorld East in Miami last year, from my experience (which I'm rolling with right now) and from studying these kinds of designs from artists around the world.
Duplicate this layer several more times and just keep rotating it (Ctrl 'T' and placing the cursor outside the bounding box). Place several of these slightly 'off' of each other by moving and rotating..
Here an exclusion blending mode creates a red effect.
Feel free to create some smaller versions (holding shift to scale down with free transform). Remember, be creative and go with it. Don't be stingy.
