This model was created spontaneously.
I tried to reproduce to some extent, but also added some detail.
I figured a smooth gray back (city background) wouldn't look good.
The clover rotates, the model is 8 dots deep and almost 1.5 meters long (6BP without 2-4 dots).
It is divided into 12 modules to facilitate transport.
Due to the clover and its different dimension compared to the original, I had to stretch the center a bit, but overall I tried to keep the proportions.
