Good God - this looks truly awful - reminds me of the sort of stuff I used to make on my BBC Computer in the 80s.
I never particularly liked their fireworks look - it always looked rather Christmassy to me. I think their Pearl Ident was the best - simple but effective (though the original shining Crystal thing was ok).
Having seen it on screen, the design isn't as bad as it looks in the caps. It is boring though. Not much creativity and the colours...well...it's hardly worth saying.
Just seen the video, they look truly awful, especially the fish tank one. I can see what they are trying to do but it looks like a BBC Micro has been dug out to make these.
It makes more sense when seen in motion, but I have to agree that if stills of this were posted in the Mock Designs forum, the creator would get absolutely ridiculed.
I think it's a bit too crude and flat. In agreement with an earlier post, I think the pearl / reflection ident was BBC PRIME's best ident. The fireworks idents that have now passed weren't too bad IMO.
