Spending the night with GLaDOS

I played the simplified flat-graphics version of Portal several months ago. Fun puzzle romp. Finally purchased the Orange Box (an XBox game collection which includes the real version of Portal) a few weeks ago, but didn't open it until last night. Wow. Nearly finished the game in one sitting (I'll complete the last two stages tonight).

( What is Portal? )

GLaDOS has been talking about a reception at the end of the trials, and she says there will be cake.
