Peter Jenniskens announced an impressive tool on the website of CAMS (http://cams.seti.org/) to visualize meteor streams in 3D. The tool has been designed by the software engineer Ian Webster for the visualization of CAMS data. You can display all showers that were identified in the March 2013 release, including the sporadic background! You can drag the point of view with your cursor to change the perspective, select different showers or zoom-in and out. Below are the Quadrantids, currently active for northern hemisphere observers.
Perfect tool to demonstrate meteor showers to the public. Have fun!
