More late-night entertainment.
The stage floor was a fully articulated hydraulic platform with integrated capacity for all kinds of pyrotechnics. Above, banks of Veri-Lites (the ones that move and change colors on computer command) were attached to an extendible arm that also moved.
The room was acoustically tuned to an installation of digitally delayed speakers, but it wasn't exactly a stadium, so I wonder if this was overkill. Cool, anyway.
