Where can I get a deep, box frame with square or oblong compartments built-in?

[erebus]

I am looking for a wall frame to display DS's knick-knacks - like his lego mini-figs, Playmobil figures or small minerals and stones.

I've found box frames for decoupage, for example, but I can't find ones with little shelves, let alone compartments! I know they exist cos I bought one in a car boot a couple of years ago.

It needs to be about 12" square or bigger, I'd say, though any size considered!

Any ideas?!

TIA

this sort of thing?

Certainly getting there! Thanks!
