Forgive the poor pictures, and the unfinished structure. This was my very very first project back from my dark ages, and I enjoyed the scaling so much but never got interested in finishing the aesthetics of the build.
Scaled Sears Tower, not only the tower as a whole but also the nine columns that comprise it. Scaled to nearly 100% accuracy. Fun little project to return from one's dark ages.
