One of the most well-documented LEGO builders out there is “Sariel,” a Polish LEGO builder specializing in Technic models: construction equipment, trucks, military equipment, etc. They feature a lot of moving parts, often with motorized and/or pneumatic power. He takes excellent quality photos and even has Youtube videos of his models.
Until now, I mostly saw his models on the Klocki blog (pron. “klosskey”) that started in Poland (and written in Polish) but has expanded to an international audience and is also available in English and Portuguese. Sariel was often featured on Klocki along with other great builders from LUGPol, the Polish LEGO user group, and Comunidade 0937, the Portuguese group (hint: look at “0937″ upside-down), as well as other great builders from around the globe.
But now, Sariel has his own blog Sariel.pl: Sariel’s LEGO Technic creations where he will feature his work in great detail. Even if you don’t build Technic, it’s still inspiring. And of course I trust that Klocki will continue to feature his work as well.
