10-pin IDC Socket Rainbow Breakout Cable

We don't really know what to call this thing - it's got a 10 pin IDC cable on one end 6 inches of rainbow ribbon and tipped with 0.1" female socket connectors on the ends. We think this would be handy as a 10-pin JTAG breakout adapter, or maybe some sort of cable re-arranger. Anyhow, it seems useful and we picked up a bunch.
