Research into plastic components

I\'d have a photograph of a group of people doing a team buidling activity designing a roller coaster using small plastic components that fix together
I\'d like someone to source the name and manufacturer/retailer of these components. Id also like to know the price for purchasing enough items to make the roller coaster in the photo. Ideally if you could get hold of a sample that would be great
I will of course provide the photo and website where i find the photo
