I push the lever further! Night and day change faster and faster! The sun is now a continuous line across the sky!

Day and night are so fast now that the bright flickering is painful to the eyes! I push the lever a little further, so the flicker is faster and I don't notice it: I must be seeing half a year every second! Or more! The sky is rich blue now, half day, half night, pulsing between summer and winter. A couple of time the room changes, perhaps re-decorated, then suddenly it drops away and I am outside! The house must be demolished! I'm travelling so fast that I must be less than the faintest shadow to the people around me!

Should I carry on, faster and faster? Or should I slow down and stop? Or go back to when I started? Or do something else?
