Circuit Simulator Applet

I’ve been playing with some electronics ideas recently and wanted a modern day equivalent (i.e., free) version of SPICE (Simulation Program with Integrated Circuit Emphasis).

After a brief bit of Googleing around I found this nice little Java applet that allows you to create circuits and simulate them.  Supports a reasonable number of components and ICs.
