    [4 May 2005] - Drempels v1.5 source code is here! [6 Feb 2005] - Drempels v1.5 is here.

    Drempels makes colorful, swirling, hallucinogenic patterns that resemble a hurricane or tornado. It normally runs in your Windows background or "desktop", replacing your old still-image wallpaper with gently-animating visuals... and meanwhile, you can use your computer just like you normally would. It uses very little CPU overhead - so little that it even runs smoothly on a 233 MHz system!

    Drempels can also be used as a screensaver; in this mode, it goes fullscreen (like a normal screensaver) instead of rendering to the desktop/background.

    Drempels works on Windows 9x, ME, NT, and 2000. It requires DirectX 5.0 or later and an MMX-capable processor.

    [30 May 2001] - Some cool textures

    I've received a lot of links to the royalty-free 'propaganda' textures lately, so I picked out some good ones and bundled them up as Texture Collection 3. ( note that the above link is to a nicely packaged subset of the textures; the official website for the textures is at )

    [14 Mar 2001] - a Drempels skin for Winamp; some cool textures

    Jim has posted a very cool Winamp skin here that lets you see Drempels through Winamp. Also, Darin posted a link to a very cool texture site you should check out. Don't forget, only 256x256 textures work with Drempels (for now); for non-256x256 textures you'll need a batch converter such as the indespensible Irfanview. (Download a few hundred textures of varying sizes, then use the 'Batch conversion' feature of Irfanview to convert them all to 256x256, 16.7-million color BMP or TGA files with just a few clicks.)

    [19 Feb 2001] - Drempels discussion forums have been created!
    [15 Feb 2001] - Tip: Instant access to Drempels or the Config Panel

    Here's a tip: to create a shortcut to Drempels on your desktop, just right-click some empty place on the desktop, select "create shortcut", and find DREMPELS.SCR in your windows (or system[32]) directory. Now you can double-click this 'shortcut' icon whenever you want to manually launch Drempels... or, you can simply right-click on the shortcut and select 'configure' to go straight to the Drempels config panel. Happy tweaking... =)

    [22 Jan 2001] - Drempels is now self-installing!

    Thanks to the generous efforts of Filip de Vos, Drempels is now self-installing! All you have to do is download the executable file and follow the instructions - no more unzipping, finding your System folder, installing textures, setting your screensaver, etc... instead, just a few easy clicks.
