I totally love the way that you've done that scroll - it looks like it's being drawn with Lasers and the effect works well.
This is definitely the most demo-like entry you've made for a challenge here so far and it's very enjoyable.
Critics hat on, you're still using primary colours, I find the music a little screechy and I'd have loved to see the DNA strand spinning instead of just scrolling up, the laser effect would have been even better if there had been some blurring.
Don't let that depress you though Tony because this is a definite step in the right direction and with a little more work on the colours and a nice tune this would be almost to the standard of Digital Watch Brawl (which I totally adored!).
