Very simple Wordpress website with animated background

The website has on top 3 tekst columns, two of these columns have to be content managed by me. The background has to be animated with 6 different letters. Full screen (square) background animation of 6 capital letters in Verdana typeface in a loop. The animation starts with a capital letter that alignes with a square background on all sides. The inital letter is slowly replaced by the following letter until the second letter takes the place of the first and so on for 6 letters the animation ends with the same image as the first. (so it can loop). Each letter has three stages: 1. appearing 2. fully visual 3. disappering Directly after the letter is fully visual the appearing of the next letter starts. The colour of the background, and each letter changes gradually from the beginning and end of each stage. The method of appearing and disappearing isslightly different in each stage.
