I had the pleasure of visiting the DDR Museum in Berlin [1] last month. I expected it to be about all the atrocities/hardship/etc but it was mainly a pleasant description of day-to-day life.
The thing I found the most amusing was the description of nude beaches. Apparently it was a point of tension between the Soviets and the Germans, but the Germans just kept getting naked and the Soviets gave up trying to police it. I can't find any great online descriptions of it, but this [2] seems to do a decent job.
