Does anyone know where to buy 'interstar' toys (do a Google image search to see what I mean, they're a bit difficult to describe!). They're coloured, geometric shapes that lock into each other, a kind of construction toy.
They are mostly sold on-line but it seems only to child-care centres, kindergardens, etc. (ie. you need a corporate account to purchase).
Does anyone know any shops (in Melbourne, or on-line in Australia) that sells them?
