Multimorphic shows off its modular, open-source P3 Pinball machine at SXSW@ 2013/03/11
The P3 is interesting for a number of reasons. First, and arguably most importantly, is the modular nature of the machine. If you take a look at the (still-unfinished) sides of the cabinet, you can see a big slit down the center, where the top can be lifted off and replaced -- since the machine is targeted toward home users, there's no concern about vandalism there. The idea is to essentially offer a platform to both developers and at-home hackers to create their own games atop what is essentially a clean slate.
