Might have some time this weekend to shoot a vid and post it up for you. I'll do my best!

Here's another vid of Daft Punk Multiball:

It's a very cool multiball if you can keep it going for a while. The key is to keep it going. As you can see, it's a 2 ball multiball at the start and as Fattrain pointed out you've got to keep hitting that disc to add more balls. You can also see you have a 15 second ball save at the beginning of it. If you haven't hit that disc a couple of times and you lose 1 ball at the 16 second mark your multiball is done (and I've had plenty of 20 second Daft Punk multiballs!). Sucks when it's only 20 seconds, but very cool when you can keep it rolling for 2 or 3 minutes.
