This is really cool. I've just posted my experiments in lighting with C2 here: http://www.scirra.com/FORUM/topic67369.html. Apologies if that just shows the URL and not a link you can click, I have BBcodes enabled but it doesn't seem to be working for me (no idea what I'm doing wrong as it previews perfectly).
I'm very impressed that you're doing the effect in just 7 events, I'm obviously doing it the hard way as mine are a lot more than that. Good work
