Andrew Gabriel expressed precisely :
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
http://www.cucumber.demon.co.uk/lights/crossing/

I had one similar at that age - traffic light, coloured bulbs and using a
purpose made rotary switch to operate the phases, I spent hours occupied
playing with it.

Nicely executed - will you be releasing the software and circuit?

Buy some lego and let the kid make his own.
Including the programming, its quite easy if you have the programmable
brick.
Its not cheap though.

Interesting -- we have boxes full of lego which is 40+ years
old stored away, but no "programmable brick". I guess my
knowledge of lego is 40+ years behind. ISTR we have some
bricks with tiny festoon lamps in them, and a motor module.

He has some giant lego, but I don't think he's shown any
great interest in it. OTOH, it's actually a lego look-a-like
which doesn't work as well as real lego. We could start
introducing real lego over the next 6 months.
