This Lego Jurassic Park set, quite apart from being both awesome design and atmospheric photography, is a custom design by Senteosan for Lego Ideas. The idea behind the site is that designers submit plans for Lego models and users vote on their favorites. Designs that receive over 10,000 votes go through a review process by Lego and chosen designs get released as official Lego products. Designers even get a slice of the profits. Previous approved Lego Ideas designs include a Ghostbusters Ecto1 and a Big Bang Theory set.
Unfortunately, despite this amazing Lego series having received over the requisite 10,000 votes, Lego has, to date, not approved the design. I think this is a real shame, as Senteosan's design is so much more creative and like the Lego of old than the official Jurassic World Lego. Senteosan's T-rex, made of multiple bricks and requiring assembly feels like a genuine Lego set, as opposed to the new, single piece plastic dinosaurs which lack the requirements for creativity and imagination that made Lego successful. Plenty has been written on how the prepacked Lego sets stifle creativity, so its a real shame that Lego hasn't taken the opportunity to give its customers what they are crying out for. Of course, its not too late. Maybe there's still time for them to learn their lesson.
