 PyPy - what's that?
 ===================
 
-xxx
+* A Python interpreter written in Python
+
+* A flexible compiler compiling restricted version
+  of Python to lower level platform
+
+* An open source project (MIT license)
 
 Motivation behind the project
 =============================
 
-xxx
+* CPython is not flexible enough
+
+* Python is so much better to write in than C
+
+* Let compiler do the hard work
+
+* Psyco/stackless hard to maintain/extend
+
+* "Psyco consumes one brain per inch of progress"
+
+Motivation - user perspective
+==============================
+
+* Noone should be ever forced to write in C for performance
 
 Status of PyPy today
 ====================
 
-xxx
+* Very compliant python interpreter (passes CPython test suite)
+
+* Can run complex python applications (Django, twisted, ctypes)
+
+* Pretty good garbage collector
+
+* JIT - in progress (more later)
