This image was made from a single image of a tail light. Rotated a little bit and sized down. A handy tip if you want to create something like this: Photoshop has this neat little tool called Actions. Basically it can record the things that you do. At the top you’ll see Window in the navigation menu. Open the Actions window. At the bottom of it there’s a little button that looks just like the Add New Layer button that’s on the bottom of the Layers window. Push it to create a new Action. You can name it whatever you want. Then hit record. Be very careful what you do because it doesn’t keep track of the Undo and Redo, so it’s a good idea to either practice this a few times of be sure of what you want to do before you hit record. Once the recording begins, it will keep track, in order all the things you change. In my case, I duplicated the original image – You can do this in several ways, I chose to hold down the Alt key and push the left arrow key. This will give you a duplicated layer 1 px to the left. I then moved it over to the left enough to see part of the original underneath. I rotated it just a tiny bit then chose Image>Adjustments>Hue/Saturation and increased the hue by 10. Once I finished that I clicked the little square at the bottom of the actions window to stop the recording. Now all you have to do is sit back and push the play button a whole bunch of times and watch the magic happen.
