My original tumblr post was here. This animation was researched by Bacchus at ErosBlog as part of the “Δ commission.” The research was originally published at Hedonix as Here is what Bacchus found.
The source Tumblr post in this animation’s Tumblr chain of attribution is at a Tumblr blog called “SOME WANEELLA’S PIXEL ART” which gives every appearance of being the artist’s blog for posting original artwork. Many animations in similar style (including some with “Waneela” in the design and some with very similar computer panel animations) may be found there.
Although little information about artist Waneella is available, one blogger has opined:
Visually, Waneella’s animated pixel art is an intentional retro callback to video games made in the 80s and early 90s. Conceptually, the images honor a time past; these images are a love letter to past days, when imagination was encouraged, respected, and rewarded.
