Think outside the box... what's the new fad?

[wutamess]

I'm looking to buy into a corporation that has the latest fad or the potential to be a fad.

Background. 07 I got into Crocs stock (the shoe CROX) and made a little money but would've come out with a LOT more if I would've waited to sell (Sold too early).

A couple of months ago, I bought into a swine flu stock (SVA)and held it for a month and gained $500... sold too late (could've came out with $900 or $1k).

I have clean energy mutual fund in my portfolio and the Climate talks has helped that sector a lot lately.

But I'm looking for other fad(s) short term stocks to get in and out within a 6 months period... Can you guys think outside the box with some suggestions?

If there's a thread dedicated to this I apologize.
