Ken Garland Toys

Couldnt really find much on this, from what i can gather though, Ken Garland design s toys (aswell as other things). His toys were designed in 1960's to 1970's, and were primarily wooden toys. However it is the connect game which i am particulary fond of. Co-designed with Robert Chapman the board game consists of small squares which house a basic line with a flat colour. I think the idea behind it is that you have to make a grid of lines that all connect with each other. By the looks of the photographed supplied too it can be played with more than one person working on it. It also seems to have endless possibilities to it, this is more or less like the 'design your own jigsaw' idea i was originally thinking of working on. I like the design of it, once assembled it has a close resemblemce to the London Underground map originally drawn by Harry Beck in 1931, which im pretty sure that is where Ken Garland got most of his inspiration from. Its a simple idea, but i feel there isnt really much longevity to it, i mean essentially, in order to keep a childs attention you keep them engaged all the time?
