Aww man, I was hoping the stuff was actually going to be drawn on the chalkboard... but that was all put on there digitally...
It was pretty cool , but they definitely should have gone with real chalk... I mean... otherwise there isn't much of a reason to do it in front of a chalkboard XD
A little grapic, but funny. I saw a video once where the people's ki blasts (energy blasts) were actually coloured and looked like the ones in the DBZ series and games. I'll try to find it again and there was also an awesome pic of it I saw a while back to, I'll also try to find it.
