Darwine is a Wine version which runs under Mac OS X. Wine is a compatibility for running Windows programs, it allows for example to use Internet Explorer or Photoshop under Linux. Previous Darwine versions were compiled for PPC but the fact that Windows apps are compiled for X86 constrained the Darwine usage to only PPC-Compiled apps (which are little to none).
Now with Mac OS X for Intel processors, Darwine can finally run X86 Applications, which means: All those Windows Apps and Games which run under Wine for Linux, should soon work under Mac OS X too (Halflife anyone?)
Here’s a screenshot from someone running Winzip:
