Mindsensors.com is working on two new devices for the NXT.
NXTHotShoe
"NXTHotShoe will allow you to trigger two cameras and/or flashguns from your NXT and you will be able to control the trigger time of each of them individually, with one millisecond granularity."
Obstacle detector
"This rugged design with ample mounting points is specifically made for NXT Sumo Wrestlers.
This sensor will provide information about presence of obstacles directly in front or front-right or front-left."
