It's our 8th anniversary of publishing LEGO® articles today! As part of our celebrations, here's a fun article from Eero Okkonen, who even explains why LEGO part 26047 is a good thing.
The basic unit of LEGO® System is not a millimetre, module, stud or plate. It is a part, or piece, or element (or sometimes probably brick, but that being also a subtype leads to confusion and turmoil). All sets and MOCs and exhibits and contest entries consist of pieces and, as this is New Elementary, we like to talk about pieces.
This little article (articlette?) goes through 8 pleasant, nice and useful pieces. There is no common theme binding them together; some are old, some are new, some are super common and some might be a bit obscure. This is not a “top 8 pieces ever” list - just a little love letter to helpful little moulds that make building fun.
