Mystical Laser Candle Lighter   (+6)  [vote for, against]
Sufficiently advanced technology is indistinguishable from magic.

This device would consist of an AI trained to keep track of candles and wicks in the room via edge tracing.* (One would have to display each candle from various angles) It would also track hand gestures. There would also be a lightweight computer, a Kinect, and a fairly small and powerful laser. When the correct gesture is performed over a candle the laser would fire at the wick, lighting it.

*This technology is quite common and has been in use for years. Please don't call "magic"

EDIT: also what [Vernon] said.

Elegant and nifty. [+]

Perhaps multiple lasers could converge on the wick, so as not to accidentally light parts of guests.

Would also work on paraffin lamps with clear glass chimneys. [+]

Voice recognition would be good ...

First point of order: [+]

That said, I wish to point out that A) the Kinect can only 'see' about 12' and B) that laser had better be tiny, quick, and spot-on accurate, or else the furniture, floors, pets, and people in the room will be playing backstop to your novelty candle lighter. Keep the burn ointment handy.

Yes, indeed.

And to reduce chances of something being between the wick and the sole laser. And to make it less obvious that a laser is being used.

You neglected to indicate that the laser should use an infrared frequency, so the beam would be entirely invisible when it does its thing.
