T-shirts

We should create some t-shirts which attract potential volunteers.

There are places with high densities of potential OLPC volunteers. Cambridge MA, campuses, conferences, etc. It might be nice to have "wearable advertising" for them. The next best thing to visibly carrying an XO. Something which brings potential volunteers forward, to talk, and potentially be hooked in.

Help us.

I'm not sure whether including wiki.laptop.org would be useful or not, as it might reduce the number of people who come forward to talk.

Mechanics

T-shirts might be made with low effort through something like CafePress (I've no experience with them). Or locally.
