We don't yet have any FP related to any video game, and I thought that this might have a chance. Placed in the right context the image can be quite informative. First of all it illustrates a feature of the game's engine (passing through a portal will not alter your momentum, but only your direction), and it also represents the sort of schematics used by the developer to advertise Portal. This type of drawings have also become quite iconic for the game.
Reluctant Oppose - the image is iconic, but only to those who watched the Portal trailer (it wasn't in the actual game). The license is quite dubious - the image is a tracing of a still from the copyrighted trailer of a copyrighted game, the portals themselves are not stylised in the Portal way, and to many people this image wouldn't make any sense. Sorry. —Vanderdecken∴ ∫ξφ11:36, 5 December 2008 (UTC)[reply]
Oppose somewhat per Janke, although I don't think diagram FPs have to be exciting. I think diagram FPs should be explanatory, simplistic, and beautiful (in the scientific sense of 'it explains a lot in a little space' if not in the sense of a aesthetics). In other words I should be able to look at it and with little or no explanation be able to figure out what's going on, and that's not the case here, because I don't understand what's going on even after reading a bit on it.D-rew (talk)
