This is an old Demo site running on Dolphin 7.4.2.
The Sliding Splash and Random Cover features are still available as free and simple to install hacks for Dolphin users, but the Random Cover feature is already a feature of Cheetah. Hopefully the Splash will also be included in a future release.
Please use this link to get a free tutorial to insert the hack.
