This is so cool! Much nicer than what we had before.

My first Google Summer of Code project (aka my first internship ever during my freshman year of college) was implementing some of the animations (like Grow) in KDE Plasma. I'm not sure I did great work, but it felt awesome to be doing it - KDE 4 had just come out, it was extremely shiny and this was the era of the desktop cube and wobbly windows as desktop compositing had just become a thing in linux!
