what is this

The main subject is the word "HELLO" in white text, which appears and changes color and style against a solid background that cycles through green, purple, and yellow. The word "HELLO" is shown with a glitch effect, then duplicated and layered, before the background shifts to vertical stripes and finally to a solid yellow, with the text remaining in the center and the "DITTY.CO" watermark fixed at the bottom right.
