When I was looking at diorama's for my QoTD earlier, I found article on speedhunters about Wilco Machiels, a Dutch man who makes amazing dioramas and models. He started making models when he was seven years old, and he is still doing it today. His website can be found here. His diorama's are works of art, and I had to show them here. They are all 1:24 scale.
As you can tell, his diorama's are all really detailed, and feature all sorts of cool shop tools, signs, car parts, and cars. The amount of detail in the engine bay of the Ferrari 250 Lusso above is pretty awesome.
I'm digging that Super 7 sign.
I strongly encourage you to check out his website: Wilco's Dioramas
