The CityEngine example project features a parisian like city with two levels of detail arranged around a 2010 logo. For instance almost each building lot is beveled somehow at corners in order to have nice running perspectives using the block subdivision parameters. Large parts of Paris were re-styled by Haussmann which earned the nickname the "Wall-City", because of continuous balconies running from facade to facade. The latter can be generated by selecting the higher level of detail.
