Don't just go wireless, try a nice deskless mouse. This $80 wireless gyroscopic mouse might work for you. The gyro feature allows you to use it in mid-air without the need for a desk/table/podium. Radio (no line of sight needed!) range is listed at 25 feet, but I've been able to use mine from futher than that. Works as a normal opical mouse when placed on a flat surface.
Requires a simple USB port and any old generic mouse driver will do. Battery life for continual use is about 6-8 hours, rechargs in one hour. The antenna plugs into your USB port; the recharger is independant and just needs any old power plug.
The mid-air gyroscopic control is a lot more sensitive than you could imagine. The first thing I thougt when I got mine was "I could game with this thing!"
Perhaps instead of 90% of the universe missing, *we're* the ones made up of 'dark matter'.
Anybody ever stop to consider that the other 90% must have some sort of structure? There's probably dark matter stars, planets, gas clouds, etc. Perhaps some sort of dark matter inteligent life as well. Whereas we are trying to figure out where 90% of our universe is, the other side may be trying to figure out where their missing 10% is.
Most of us here belive in some sort of extraterrastrial life. I doubt many of us are naive enough to belive that life only exists on a small blue planet in the backwaters of a single galaxy. Considering dark matter occupies 90% of the mass in the universe, I think it would be naive to assume that life consisting of dark matter doesn't exist as well.
Oh well, it's just a random thought. We can't (yet) even prove the existance of dark matter, let alone manipulate and study it. Observing and contacting a civilization composed of dark matter would be all but impossible.
Wouldn't it be funny if *we* are actually the strange aliens composed of the 10% of mass missing from the 'real' universe?

Check out this article over at LLNL for a bit more info. Apparently their 1.25 petawatt laser only takes 600 joules to fire for half of a picosecond.
