Video Game Interlude - Coolest Ever!

I was playing Tomb Raider: Underworld DS this morning and came across a part where I had to clear some dust away from a stone tablet. As it was the first time I had done that in the game, the tutorial came on and told me how to do it. The cool thing is that I ACTUALLY BLEW on the DS to clear away the dust! I guess the microphone senses the sound and makes the dust move. Ah, modern technology! Now I REALLY want a Wii for Christmas!!
