HTK#21: Citiblocs construction with huge snail inside circular bridge with dominos

This is my first constuction at MJC. The company citiblocs gave me 6000 planks to make this construction. The room is lend for free by the MJC of Villeurbanne (maison des jeunes et de la culture). The video took me 23 hours of construction (i don’t count pauses and tidy up) Notice that as i am a geek, the bridge has 21 towers and 2 levels, which is 42 links. But this was not made on purpose, it is just pure coincidence.
