The Sockets code sample is explained, in English this time, in the following article: Visualization of Real-Time Data Using Vector Graphics. The sample uses TCP/IP to communicate simulated real-time data changes from a server to a client. The client uses VG.net vector graphics to visualize the incoming data.
The article explains how to create 3D-effect LED components, using techniques similar to those described in the Gel Ellipse post.

In the upcoming version 2.3 of the VG.net vector graphics system, we made a significant performance improvement in complex displays with many objects and simultaneous animation in multiple portions of the screen. Download and run this simulation of a mixing process, which has been linked with version 2.3. Formerly this demo took close to 100% of the CPU; now it takes about 0%, with occasional spikes.
An interesting post about the performance of Avalon vector graphics appeared on the newsgroups today. I posted some results from the VG.net Scalability test for comparision.
