Steve Freeman and Jamie Dobson are running a session at SPA2012 [1] which should yield some interesting results. (It was also run at last weeks Software Craftsmanship conference, but without the time to compare results.)

Each pair builds a software enigma machine - but they can build it however they like. This results in multiple approaches to the same problem. Some TDD, some not. Some in OO languages, some functional. Some paying close attention to design, others just trying to finish the task.

They want to evaluate how the design of code is affected by the starting conditions. 

We want to evaluate how the existing design of an application affects adding new functionality.
