LavaPS is an interactive process-tracking program that visualizes system load as blobs of virtual, non-toxic lava. Like the Bubbling Load Monitor, LavaPS tries to present important operating system information in a graphical analog form that is visible in the background, so that you get a rough idea of what's happening to your system without devoting much concentration to the task (the program was inspired by Mark Weiser's ideas about calm computing). The blobs correspond to processes in the system, and represent different metrics associated with processes. Their size is proportional to the amount of memory the process uses, and their movement is proportional to the amount of time the process runs. Their color corresponds to the name of the program which is running, and they get darker when the process doesn't run. Over time, the process will become nearly black and only its border will remain colored. Finally, if both physical and virtual memory are shown, then the part of the process will be a slightly different color showing what percentage of the process is not in physical memory. LavaPS runs on Linux (here is a Red Hat RPM), and is Open Source (here is the source code tar file).
