Escalators

Brief

This is a contest specifically for escalators. Stairs and stairwells are quite a popular subject for photographers, but this contest is for only the moving ones - please give us your best effort on this specific subject. There needs to be more than just a few stairs but the photo can be taken from any direction. Use symmetry and composition to its best effect, colour or black & white. Please do not include photos of travelators (the flat, moving walkways).
