Nice spinny stuff
A 0.92T 0.23
1Looking at the animation, I can see a heart shape made of pink dots that appears to be "drawing" itself - dots appear one by one tracing the outline of a heart shape, with the leading dot being slightly larger/darker. The heart is positioned in the upper-left area of the screen, and the animation loops continuously.
