I'm sure it's nothing new but I've been noticing alot of 3D renderings of printed circuit boards lately so I decided to find out if there's a way for me to do it with my Eagle PCB boards.  After a bit of searching I found a free ULP for Eagle that allows you to create pov files for a program called POV-Ray.  POV-Ray allows you to render 3D graphics with stunning quality and is free.  In about a half hour I was able to download and install the ULP's, POV-Ray, and create a top and bottom of one of my simple circuit boards. 

The board I rendered is a breakout board I created for my Teensy 3.0 microcontroller (which is pretty awesome by the way).  I needed a 16 channel multiplexer (MUX) for a project I was working on and needed to make it fairly quick so I decided to make it at home instead of using OSH Park.  I had some 74HC4067 IC's in the DIP24 package so I made up a schematic in Eagle, created a PCB then etched a board.  I also have a dual layer PCB version on OSH Park you can buy and assemble yourself.  If you use the optional pull-down resistor this breakout will allow you to multiplex 16 signals to 1, or 1 to 16.  The signals can be analog voltages or digital logic signals and the breakout can operate using a supply voltage between 2 and 6 volts.  The biggest advantage to this breakout is that it can give you the ability to have 16 inputs and use only 5 pins on your microcontroller!

And, here is the actual working prototype single layer board.  It's not as pretty as the 3D rendering but close.
