Most of the people I ask know what phun is... but anyway, the awesome physics sandbox made by emilk has now been sold out to a big company, and to get the full features you must buy, buy, buy.

if you don't know what phun is, google it.

Ok, there is a new release of phun, but there are no lasers, and no cropping by alpha of images (I really need that ). The company that bought phun and renamed it "algadoo" is called Algoryx.
