Two things that made me go “wow” today

1) A lovely demonstration of combining water and sound waves. The pictures and video are gorgeous. Looking forward to trying this out myself. See the details here: http://www.thisiscolossal.com/2013/03/this-is-what-happens-when-you-run-water-through-a-24hz-sine-wave/  

2) A real-time world map of Tweets. Worth looking at this on a large screen and wait to see the network patterns to emerge. See the details here: http://www.tweetping.net/
