It's a rather obscure project, actually. It's firmware to convert an Atmel development board (micro-controller based, small programmable ICs) into a portable programmer for other Atmel AVR micro-controllers and Dataflash non-volatile memory ICs.
You can check it out at [link] in the academy section (project name "ButtLoad" ) but I warn you; to non micro-controller people it's pretty dull!
I've used your icons in the current development version to give the manual a little pizzaz. I've included a link to this page at the end.
