At a product vendor fair today during the ADA conference, pioglitazone maker Actos made it clear to me that multi-tasking with a penlight can be both fun and productive. The dual snake penlight/laser pointing device can be employed for a majority of tasks, most typically to doubly highlight extremely important points during talks or, while using the LED light to read papers in dark corners of the night, to "virtually underline" text with red laser.
A brief demonstration of the "hands-free" lighted reading paradigm. Guaranteed to impress your colleagues at any time of the day.
Actually, it is a pretty cool contraption, maybe useful for some quiet reading on a late-night shuttle ride home.
