My friend accepted a job on rentacoder that required him to remake the adobe acrobat toolbar system using Java. At some point he decided not to go on with the project and asked if I'd do it for the pay he was being offered. I accepted and started from scratch. The program actually ended up being very complex, though it may not look it. I'm actually rather proud of the final product, it works nicely and seems 100% bug free.
