The third dimension is a growing topic at OSM. It's already possible to add detailed buildings and a lot of minor objects, which results in a 'feeling like home'.
If you just want to browse 3D city models, you can view them with multiple tools:

Quick access to demonstration areas are also available on the Simple 3D Buildings page. A similar list of map applications can be found on Simple 3D buildings page.
For artists, it might be interesting to get city models in common 3D formats as .OBJ
The process of detailed recording your environment for later modelling is called micromapping in general. To get a lot of details very quickly, the Photomapping technique is recommend.
Instead of taking your own photos (from top of tall buildings), you can watch for your area at Wikipedia Commons or ask e.g. Wireless Community networks. Some further image services, which are worth to check:
To enter the data of your city, you can use OSM itself, or use an external storage.
Additional list of 3D tagging applications can be found on Simple 3D buildings page.
