Stardock is working on DeskScapes 1.01 which is now internally being tested. The next public release will include dynamic and triggered content with it to help get the ball rolling on that kind of content.
Stardock will also be releasing an updated DreamMaker which will make it easy (full GUI) to create your own triggered DREAMs.
Regarding Microsoft's Windows DreamScene, we don't have any official word but Microsoft is aware that some users have run into problems when the default MPEG encoder has been replaced by a different one due to installation of third-party video players. This should not be a problem in the final version of Windows DreamScene.
Also, we should also mention that Microsoft will be releasing a number of DreamScenes when Windows DreamScene is officially released. We don't have any official dates from Microsoft on the official release of Windows DreamScene.
For dynamic content, Stardock DeskScapes will still require that Windows DreamScene is installed. In our tests so far, dynamic content (at least the type we've created) is using less than 4% CPU on average on a mid-range PC.
DeskScapes 1.01 will be available in beta hopefully within the next week or so for users of Object Desktop via Stardock Central. Stardock will also be releasing a premium DREAM on Stardock Central for Object Desktop users as well.
Once 1.01 has been tested, it'll be released with the updated DreamMaker and Dynamic Dream SDK including source files to create your own dynamic content.
