WARNING: This page contains a lot of flashing lights and bright colors after the scroll.
1x1x216 is a single-pixel animation which scrolls through the original 216 web safe colors. Below, the pixel is set to stretch and fill the width of various containers on Squarespace. As each instance of the gif is loaded at a different time, displaying multiple instances of it will create unique flashing patterns that reflect the viewer’s internet connection / browser speed. Scroll down to view it a few ways; refresh and see if your patterns change.
