The amalgamation of futuristic technology with prehistoric settings and creatures has always produced entertaining results - think Jurassic Park. Keith Goldman's latest brick-built scene is another beautiful example: a rather unfortunate speeder-bike pilot is ambushed by a Dilophosaurus while his comrade makes a high-speed getaway.
While the repetition of pieces and techniques (such as all those green Exo-Force spikes!) gives a sense of the vast scale of the prehistoric forest, there are plenty of small details that stand out too. The weaving together of several yellow-orange tooth plates produces a fantastic prehistoric plant design; I love the ammonite printed plate on the front of the lead speeder, and as Christopher Hoffman pointed out on Flickr, the fit between the ski and the ingot element on the underside is "goddamn beautiful." I love this build.
