Seeing those engines start up is like watching some organism come to life.

@losability That's called the twang. When the main engines ignite, they provide 1.2 million lbs of thrust at an angle, so there's a horizontal force on the shuttle. This causes the whole stack to bend (since the SRBs are still attached to the ground), and then bounce back like a spring. When the stack returns to the vertical, the SRBs are released and ignited (virtually simultaneously). The twang causes the top of the tank to move something like six feet (seen here: watch?v=ExfjSuJxOP8).
