NetIcon for Windows
NetIcon is a little utility that sits in the Windows task bar
and shows your network throughput. You need to have WinPcap
intalled. Net Icon was modeled after Process Explorer, which only
shows the CPU and IO load.
Additionally it shows a "netblob" diagram with the address of a packet and the size mapped to a hilbert curve.
As the packet "ages" the color cycles and fades to green.
A map show the geographic location of incoming/outgoing packets.
Try out the beta version for NetIcon release 1.6.
