Firewood is a free online log-chopping simulator: rounds of firewood are placed upon an old stump and you must use an axe to chop them into appropriately-sized splits. Rounds come in various sizes and heights. The full-window graphics are surprisingly good and the vibe clusters around "satisfying," "peaceful," and "cosy." Sadly, it doesn't seem to let you do badly: I would have liked to have made some ridiculously thin logs, to have to free a stuck axe by hoofing at the log, or to have had the opportunity to dismember several of my own fingers.
It was created by Gavin Shapiro (instagram), who has made several other similarly good-looking and odd distractions to play with online (previously at Boing Boing). Poms is wonderful. Go spawn yourself some pomeranians!
