Thought some of you might be interested in a toy I made for
a 2½ year old for a Christmas present -- a working model
pedestrian crossing. He had just started getting fascinated
by traffic lights and crossings, and this seemed like too
good an opportunity for an educational toy.

There's a detailed description and pictures at

How times change, my old chap made me something similar 50 odd years back
using Meccano.
I turned the little handle which rotated a wooden 'cotton-reel' wrapped with
a piece of tin-can cut to shape to give the correct sequence, with spring
loaded contacts.
