Check it out folks, a real life air guitar that you can purchase. I saw this, and had to laugh. I wonder if they’ll make different styles of these eventually – because I’m holding out for the Les Paul air guitar – this one looks pretty cheap anyhow.
If you’re really into air guitar-ing, be sure to check out this video from the air guitar world championship 2006 – this dude shreds!!

I should have mentioned – the air pick too! what a bonus!!!
And I’ll chime in with a plug for To Air Is Human, a hysterically funny book on the subject, by Dan “Bjorn Turoque” Crane:

(The liberry has it, too.)
