Wow. That's quite a way to address visitors: instead of providing alternative representations that would pique the visitor's curiosity about the missing content and motivate them to install the required plugin, you're insulted for being backward. Quite a strategy. Of course, something like this could only happen on pages like those of Hamburg Medial School.
If media designers of the future are being trained there, we're in for a lot of arrogant bunglers...
