This is an experiment in Chrome, so you will need to install the Chrome browser if you do not already have it. You can search for accounts or topics, which are then tracked through time and visualized similar to how a particle collider draws pictures of subatomic matter. After the data mapping is complete, if you hover your cursor over the data point, you will see the information for that data. One amazing visualization is from a search of the topic #epatcon.
Data point particles are mapped two dimensionally based on their position in time (vertical axis) and search query (horizontally). You can search based on user, phrase or trends.
This video shows the basic idea of how it works:
The Social Collider web site explains the experiment like this:
If you have not yet used Social Collider then you should try searching for different names, topics and trends. Go ahead... experiment!
Update - here is some interesting visualization on a search for #w2s:
