Multicoloured Councillors Part III - Epilepsy

These colour effects are fabulous (unless they switch to Eye of Sauron mode) but they they can be hazardous to anyone trapped inside the building when they start. Cleaners and late-working councillors who stay beyond dusk report being trapped inside a giant disco ball, and they can't help but dance through the night, and are often found the next morning exhausted, lying on the floor, but still gently shimmying as if listening to 1970s music.
