Are there projects visualizing and analyzing historical transaction data?

I know blockchain.info etc, but I'm looking for things beyond simple timelines of transaction volume and the like. I was thinking towards scientific projects that aim at discovering patterns in the historical data, for instance:

are there addresses that accumulate large amounts of btc?
are there interesting transaction pattern, e. g. prolonged transaction "ping pong" between address pairs, "star patterns" where a single address sends out transactions to a large group of others, etc
are there amounts that seem to get passed on along a long chain of addresses?

Note that those are just examples I made up to illustrate what kind of angle I'm looking for: a more open-ended, scientific analysis rather than trading advice. That same notion makes it hard to search for projects, so I'm hoping that someone might happen to know something.

Your problem is the "things like that". There are lots of different things that might be of interest to some people and not to others, and so each site has a few reports or charts but none are comprehensive.

Two examples: blockchain.info has a number of reports in the bottom right of their main page under the 'Other Bitcoin links' that has some reports that some might find interesting. Bconomy has a number of charts that provide information about blocks and transactions.

I understand. I rewrote the question hoping to be more specific this time. – Hanno Fietz – 2013-07-02T15:00:01.510
