Mozilla has announced, in a stroke of original genius, that they’re working on a “web on the desktop” application, they’re calling Prisim, to compete with the likes of Adobe Air, Microsoft Silverlight, Konfabulator, Apple Widgets, Google Gears and Microsoft Gadgets.

How will they be different? Well they say their platform won’t be proprietary, that is “they aren’t trying to replace the web”. Prisim is based off of the virtually unknown Mozilla Labs Webrunner. Prisim will eventually be available for Windows, Mac OSX and Linux, but currently only a pre-alpha Windows build is available.
