This is pretty straightforward. There are a number of online tools to allow you to do this. I used http://www.autotracer.org/. This site allows you to upload the URL of the image you would like to render and then save the file. Then I used Autodesk's online DXF viewer to view the image before sending it to a laser cutter.
Since Pokemon GO came out, I've wanted to make something to related to the game. I wanted something I could make in an afternoon that I could use right away, so I thought of a blinking Team Valor badge to represent the best team in Pokemon GO. The circuit is simple, I am using a square wave oscillator that is driving an NPN transistor which lights the LEDs. The real challenge comes in the enclosure. I laser cut a cut-out of the Team Valor Emblem and glued it to one side of a piece of non-glare acrylic. When the LEDs turn on, the emblem is displayed in all its glory.
All the materials should run you about <$10 (minus the laser cutter of course and soldering tools)
