Give Away Free Time

I was just looking into various tools which uses computers' free time for various projs.

How about making use of little time of ppl. with little/medium computer knowledge into useful things ? Is it possible ? Is there any work which can be chunked so that it can be done/partly done in little time and also it should be able to be continued by a brand new person ?
