Green laser points the way

A pointer that finally makes sense

Jasper Laser

We're old enough (unfortunately) to remember when laser pointers were new and expensive, not the kind of bargain-bin item you can find at OfficeMax. But even though they've become surprisingly affordable, we've been disappointed at the preponderance of laser-pointing objects that make little or no sense.

That's why we appreciate the "Jasper Keynote." It's a laser pointer with a built-in radio transmitter that can let you point and run your PowerPoint presentation simultaneously if used with a USB receiver. And the best part of all: It's green (our favorite color).

Thanks to I4U News, we also learned that the human eye is roughly 50 times more sensitive to green than red. There'll be a quiz in the morning.
