Does anyone want to give this little guy a go?  I was given this to try a while back but never really took to it.  It's a heads-up display for either heart rate (HRM included) or your Ant+ power/cadence/speed sensor that uses small LEDs at the bottom of your field of vision to communicate your performance relative to target.

If you'll use it, make me an offer- interesting trades (including 170mm mountain cranks) will be considered...
