An avatar contest about human erections. Awesome.
My entry is a mix of the old and the new:
The Kaaba, located within the Masjid al-Haram, the world's largest mosque.
Overlooking it is the Abraj al-Bait tower complex, one of the world's largest buildings, whose hotel tower is the tallest clock tower in the world and with the largest clock face in the world.
All in Mecca, Saudi Arabia.
