James Gosling has just launched a few t-shirt designs to hold Oracle to their pledge to free Java. The CafePress store has a number of different tshirts all with the tagline "Just Free It. Hold Oracle to their Pledge", along with some mugs, buttons and magnets.
As James Gosling writes in his blog post:
If you're attending JavaOne or OpenWorld, I'd appreciate it if you'd wear one, just to let Larry know that you care. Or if you just happen to be wandering the neighborhood (I know that there are lots of Java hackers who work within just a few blocks of Moscone). Or if you will be spending quality time with an Oracle salesperson. Or in any other situation where the spirit moves you. It's a gentle but clear way to express your feelings
There is one more design on the page, featuring Larry Ellison with the slogan "We're Long Past 1984".
Perhaps we'll see a lot of these tshirts in circulation at JavaOne this year, although we're not likely to see any on Google employees.
