How to comprehensively block lunchtime pedestrian traffic within Sun’s main office concourse:

1. Position yourself at a prominent table next to the coffee shop, in the concourse area in building 2, en-route to the cafeteria.
2. Wait until any of a number of geeky colleagues and friends happen to walk by.
3. Wave a copy of Make Magazine in the air, waggle your eyebrows and exclaim “turn your old analogue mouse into a minature robot!”
4. A critical mass of geeks will coalesce within about 5 minutes, preventing cafeteria access.

Take great care when attempting this stunt, lest the marketing department starve.
