Black Eggcrating: where in Vancouver?

[SteveW]

I'm trying to find black egg crating for the top of my tank (I just found a clownfish on the floor and want to prevent more jumpers!).

I find the white a bit distracting but can't find any BLACk eggcrating. The metallic stuff looks risky to me (and probably too shiny for the top anyways).

Any ideas for the Vancouver area?
