The Holy See has published a spherically 360º panorama of the Sistine Chapel interior (Web). Use the arrow keys on your keyboard or click-drag your mouse to move about then use the mouse scroll wheel to zoom. The detail is amazing! I once saw a really nice replica of the Chapel in Second Life, but I can't remember where.
Footnote: Geometricians are welcome to tell me the correct term for a view that is "spherically 360º" in appearance.
