I first made the 'falling skulls' compiz theme back in 2009, along with my 'futuristic' 'glowy' Emerald themes. Of course you could make the 'snow' textures into whatever you wanted, and the skulls falling in front of a mushroom cloud was pretty cool, or at least I thought so at the time.
Then compiz died, and we've all been living without burning windows and desktop cubes ever since. A couple weeks ago, for whatever reason I tried installing Compiz from apt, and to my surprise everything worked! (Thank the Compiz Reloaded project for that.) I said, 'Sweet, I can get my 'skulls' theme working again!' So I went to gnome-look.org and dug it up, along with my Emerald themes, and made a Puppy remaster which loads Compiz at boot with no configuration required.
Then I was like, 'hm what else could you use the snow plugin for?' and thought of the hot air balloons, downloaded the images from unsplash.com and edited them in GIMP. The snow plugin settings allow you to change the textures to moving upward instead of down, and turn off rotation. So that was how I made the 'balloons' theme. Looks pretty realistic, hey? Similarly, the settings allow you to go left-to-right or right-to-left, so I used that to make the undersea 'fish' theme. Etc.
Then I made the Switcher app, which changes the compiz settings with a push of a button, and uses gsettings to update the desktop, so you can switch between themes on-the-fly, without restarting Compiz or logging out. Are there any other theme selector apps for Compiz?
The .deb detects if you are running Puppy, and if so installs the config files to /root, and if not (i.e. a regular Debian system) installs them to ~/. Speaking of which, the switcher.deb has been tested on another popular Debian-based distro with XFCE, and can use XFCE4 commands if one is using that distro. For Puppy, it uses set_bg. It is also supposed to use 'feh' if available, but I haven't tested.
Oh, and before anyone says anything, if you use Komorebi for the video backgrounds, you have to right-click the desktop to access its settings or turn it off. Works great with compiz, though. Only bad thing about it is it doesn't detect the desktop shortcuts created by eventmanager, so you can't see your drives without turning it off.
