There has been construction underway at the excellent Gwangju Bus Terminal for a while, as they're putting a few more floors onto the east side. When construction finishes in May there will be a music hall, a performance stage, and Gwangju's first IMAX theater. Wikipedia explains what that means:
IMAX (short for Image MAXimum) is a film format created by Canada's IMAX Corporation that has the capacity to display images of far greater size and resolution than conventional film display systems. A standard IMAX screen is 22 metres (72 ft) wide and 16.1 metres (53 ft) high, but can be larger. As of 2008, IMAX is the most widely used system for large-format, special-venue film presentations.
Below is an artist's conception of the site back in 2007; you can see what it looked like last month from these photographs.
