The Pharo project wants to take a fresh look at the Smalltalk philosophy and current implementations. It wants to produce a clean and lean open-source Smalltalk.
It will start from Squeak but pharo is a fork. An important test for pharo is that Seaside should run on it.

As far as I know the project is named after the famous lighthouse of Alexandria, but this was called "Pharos" not "Pharo". Time for a bug report?
