Never heard of hackathons? Wikipedia defines it this way:
A hackathon refers not simply to one time hacks, but to a specific time when many people come together to hack on what they want to, how they want to - with little to no restrictions on direction or goal of the programming.For all the details and for a great FAQ that Jeff crafted up please see the EclipseCon Hackathon page.
Events like these that I have been involved in the past have been challenging, rewarding and FUN.
When you need an interrupt from the technical talks, I would encourage Eclipse committers to bring your laptops, ideas and talents to come do some hacking.
