I didn’t play with the M:TRON theme as it came after I have put my bricks on the shelves. My era was really the early Space Classic.
However, during my hobby of rebuilding my old LEGO sets, I came across M:TRON and was fascinated with both the limited amount of sets and the very bright colour theme.
By chance I got hold of two M:TRON astronauts and some trans-neon-yellow panels and I decided to make a small greenhouse type facility. I have no idea if the style matches M:TRON (or the other sets from that time period) but I’m quite happy with this one.
