I'm a huge fan of LOAD81, its been a very interesting too for a few things .. one thing I've used it for is to view system statistics, akin to a poor mans gnuplot. Its also been valuable in teaching my 7-year old about computing - the ease with which you can bang out a program to draw stuff is very appealing. So count me as a LOAD81 fan, antirez .. its one of your side projects that gets regular use around our house!
