I have no idea, but I guess that it was built because it was technically feasible. Xgl [1] was released in the same year and had quite similar capabilities [2]. Xgl, in turn, lead to Compiz/Beryl which is the technical ancestor of the most popular window managers we run on Linux desktops nowadays (e.g., Kwin in KDE). So to some extent, we still use the tech which was developed back then, the effects are just a lot more subtle.

Likewise re: subtlety, the Windows Vista/7 Win+Tab animation used a 3D card stack, the Windows 10 ones uses a simple zoom-out. Both are 3D, but people seem to prefer the ones which don't scream "3D!" as much. There's acryllic everywhere too, which is blurry transparency, but you might not notice it either. That said: I miss Compiz wobbly windows. They were cool.

  Wobbly windows and cube animation for extra oomph! :-)

    Ah cool. I miss them because I jumped off Linux and switched to OSX/macOS for a few years and then moved to Windows. That said, I just found https://www.stardock.com/products/windowfx/ https://www.stardock.com/products/windowfx/

    wobbly windows is so 2006. Enjoy clothy windows. https://videopress.com/v/zmiBKUyQ https://videopress.com/v/zmiBKUyQ

      For bonus points, Arcan & Durden are a lot more hackable than Xorg & Beryl :-)

        at the very least, they'll have to work -hard- to get it as easy to hack as https://github.com/letoram/durden/blob/master/durden/tools/flair/cloth.lua https://github.com/letoram/durden/blob/master/durden/tools/f... :-)

        Is this using LuaJIT or just plain Lua? Because I get the impression this (not-C, not-Rust, not-stereotypically-fast) code is what's running at 60(?)fps, doing the actual deformation animation. Nice.
        crazyloglad 8y ago
        Both are supported, but it's not particularly heavy - it's only running at a monotonic clock of 25Hz (decoupled from display updates and deliberately chosen to not be evenly divisible with 60Hz to pinpoint animation issues). Alas, the improvement that should really be made is to encode both n and n+1 in the same update and interpolate in the vertex shader, not hard here but I was lazy..

    Wobbly windows are definitely available with Kwin 5.13.5 (September 2018). I love that effect too, so it is always enabled on my PC :-)

    I think most compositing window managers do, having adopted a lot of plugins from Compiz and Beryl.

Xgl was attempt to do the same thing by SuSE, which led to lot of opposition from other Linux distributors. This spawned competing AIGLX project (mostly associated with RedHat in that times), which solved the same "problem" from the other end and enabled such graphical effects mostly as an side effect and in contrast to Xgl without degrading performance of OpenGL applications (Xgl did not allow it's clients to use hardware acceleration). The difference is that both Looking Glass and Xgl works as an proxy X server. While AIGLX was an effort to make client-side libgl implementations usable from the X server itself, which is good for Acceleration of GLX in Indirect mode (hence AIGLX) but also as a general HW acceleration backend for things like XRender and XVideo (for example intel driver emulates XVideo in terms of OpenGL) and with addition of one simple OpenGL extension (ability to create GL texture from contents of X11 window/pixmap) allows all the 3D window manager tricks.
