Just stumbled upon this, a 2000+ m high 'virtual tower' with 406 residents and constructed out of top-quality pixels ! All floors seem to be added on request and each floor represents an establishment with it's website and email available next to it's 3D shot.
Unfortunately, Mr.Wong's Soup'Partments has stopped leasing on Nov 21,2003 just a year after it was launched (according to the website). You can,however, visit their apparel website. Check out his website for his latest projects.
