Via Comics Worth Reading: Boom! Studios has released its Cthulhu Tales vol 1 as a free webcomic (interesting set of short stories here). Unlike other places releasing stuff for free , this one is not locked to any particular geographical region. Comics it seems, like Cthulhu, dream a mad dream of one dark day finally being free.
EDIT: Ross Richie of Boom! studios tells me that they are gradually releasing a page a day of this little gem, so be sure to check it periodically.
