Lego
Saw a programme about Lego - they were on the edge of bankruptcy and now are worth billions
Lego is good for children and the adults love to create too
A guy from England created 'birds' for the Lego team to have a look at, fortunately they loved the idea and now the lego birds are selling very well - they did look good
Might give this a go meself
I preferred Meccano as a youngster but it looks like Lego is as good now ...............
