We know what you're thinking: "That is awesome... what is it?"
This is an Arduino shield with pogo pin connectors for each and every GPIO.
It's essentially the same rig we use to develop and test shields over at SparkFun!
The pogo pins allow you to connect an Arduino shield to the dev board without having to make any solder connections: simply connect the Pogobed Shield to your Arduino, place the test shield on the pins and twist the tabs to lock in the flavor.

This Pogobed Kit is especially useful for anyone who is developing or testing Arduino shields but it has plenty of other uses as well. Prototyping without having to solder to a shield is really handy and if you have one Arduino that just sits on your bench as a development platform, these pogo pins will wear out a lot less often than the female headers.

The Pogobed Shield also breaks out the reset button and status LED from the Arduino so you can still access them when there's a shield on the jig. There's some prototyping space as well, which will come in handy if you plan to use this as a test-jig.

The Pogobed comes as a kit so there is some assembly required.
