And the maple leaf window feature is a definite flop. I asked the BoC rep how to check the feature and she recommended using the flashlight on an iPhone 4. Spent an hour testing different lights and couldn't find it. What's the point of a security feature if it can't be easily checked?
You need to use a bright, small point of light surrounded by darkness. The smaller and brighter, and the darker the area around the light source, the better the effect. You need to hold the note right up to your face, as close to your eye as possible, as you look through it.
Try a distant street lamp at night, or a pinhole in a sheet of aluminum foil in front of a bright lamp. That should do the trick.
For a few years I've had a pair of novelty glasses that do the same thing - make Santa Clauses appear around small bright lights.
