About Liquid// I really think this one had no origin story other than that I wanted to see if I could make it. I wanted to create a really dynamic and fun to play with water-like surface.
I started with string of Sprites with 3 forces opposing on each simultaneously onEnterFrame: gravity (attracting to their origin), cohesion (attraction to their neighbor Sprites), and disturbance (repelling from the cursor). It took a lot of playing with those numbers to get it to behave just right. I then went ahead and tried stacking layers of it with decaying amounts of those forces to simulate perspective, and then finally applied the effect to a closed circle.
In the end I realized it was pretty fun to mess around with, although I have never been able to apply it to any real project other than when I snuck it into the preloader of Neffworld.
