We posted the video yesterday, but turns out there’s a secret message embedded in six frames, at about 1:24 in the video.
Follow the headline link to the video, pause, then drag the slider to about 1:23 in. Now press period (“.”) to advance one frame at a time until the Easter egg comes into view. Have patience, might take a good number of frames to get there, but it’s there, I swear.
You’ll find all the details in the original Reddit post.
