The latest version of CDER does not require py-lepton, as the library has not been adapted to 64bit environments. Launch with
python CDER.py
just like any other python script. This new version is intended to be architecture-indpendent. Let me know if you run into bugs.
CDER (ColliDER) is a particle physics event visualizer focusing on high-level objects such as fully reconstructed jets and leptons. The purpose of CDER is to explore the topology of physics processes. CDER is designed to be fluid, simple and pretty. It makes extensive use of the following packages, which must be installed locally
http://code.google.com/p/py-lepton/
CDER itself does not need to be compiled or installed. It should run out-of-the-box given that the three packages mentioned are installed and working.
CDER is placed under the GNU General Public Licence
There is a video introduction to CDER on YouTube

CDER does not yet run in 64 bits. Run in 32-bit mode (python-32). This is because of the nature of the super-fast random number generators in py-lepton. This should be fixed at some point in the future.
To launch CDER with the example events:
python-32 CDER.py
