Oh man, compiz-fusion is what got me interested in Linux. I remember seeing videos circa 2007-8 of people's desktops with all sorts of crazy stuff. Cube desktops, wobbly windows, fire trails, etc. I spent forever figuring out how to dual boot Ubuntu 8.04 and Windows and learned a ton so I could setup these effects. Fast forward 12 years and now I only use Linux on servers without a desktop interface at all.

While this stuff may seem silly and pointless, you'll never know who it'll inspire to dive in to a whole new world. I'm glad it's being maintained still

I am using Wobbly Windows right now in KDE. Desktop Cube works too but I don't like it (I use 16 desktops instead of 4 :).

When I have to use Windows every once in a while I am viscerally disgusted by the lack of wobbly windows. Moving windows just feels wrong - very, very wrong. Takes a second to realize they're not wobbling. To me it makes the computer seem less robotic and more natural in a way, I guess. Like haptic feedback on smartphones when you tap stuff.

I don't know about you, but I've been running wobbly windows up until about a month ago, when I disabled KWin's compositor in favour of picom for performance reasons. I hope to get them back when I'm able to start using KWin on Wayland.

I still use both on KDE Plasma desktop. Life is great.

Many other options like fire-on-window-close and zooming are also available.

I believe you could get them just using kwin the window manager.
