Thermometer/Laser Pointer Mouse
If there's one thing I want my computer mouse to do, it's tell the temperature. And also work as a laser pointer. Oh yeah, and it would also be nice if it would control the little pointy arrow on my computer screen for me, and be easy to stash away in my bag due to its retractable cord. Oh look! The mouse of my dreams is this Thermometer/Laser Pointer Mouse! Finally, a gadget incorporating several functions that I've never ever considered essential to mouseness. $16.99 USD.
