Bit of a late entry to the "Without borders 3D Visualization Challenge". I've looked at this tower for many years, as it is well visible from most directions, even from a long distance. Especially by night it starts to stick out with colorful lighting. The building has a colorful history itself. It is located in Frankfurt, Germany. Started the project with only a few days to finish, after seeing a reminder;) .
