"8. audiovisual mappings" demo is broken

[rahji]

When executing these lines, I get errors in the console and the effect of changing the radius of the sphere does not work:

sphere = Sphere().render()
kick = Kick().trigger.seq( 1,1/4 )
sphere.radius = kick

First line gives the error: ReferenceError: sphere is not defined

Third line says: ReferenceError: sphere is not defined
