"Researchers' night" in Prague

There was the Researchers' night in Prague, reportedly already for the third time. I went there for the first time, with some other people as well.
It took place yesterday near and in the Prague TV tower. The program was perhaps rather poor, it almost seemed to me that it was just necessary to join a European event.
Nevertheless, there were some worthwhile points.

• There were a few of nice Physics experiments.
• There was a painting exposition of a scientist, I just loved his style.
• There was a machine to measure one's posture just from his feet - rather interesting; there was a lot of people waiting for it so I couldn't try it, but it seemed really sophisticated.
• There was a possibility to measure one' glycemia and blood pressure. Ok, results don't indicate that I've been yet dead, but...
• And the best part was a meeting with a few scientists (a chemist, informaticist, statistician and a historician) - not perhaps that much informative (but some prognosis were at least funny ;-), but good to hear their opinions)
