They are regular RGB LEDs that are wired together into a matrix via their leads. If you look closely, there are 16 panels of LEDs that we see end on for much of the video. To address an individual LED they use the panel, row, and column numbers. I have wanted to build one of these for years, but it's terribly fussy building all the panels. Most folks use various forms and templates to get the LED leads bent just right and the LEDs all evenly spaced. Oh, and the silvery LED leads and solder help disguise all the connections that are there.
