Hi,
mfoxdogg has been experimenting with the GLSL stuff in the apricot branch. You can find his experiments in his Blender Labrat blog at http://blenderlabrat.blogspot.com/2008/05/glsl-in-apricot-branch.html (also aggregated on http://www.planetblender.org/ )
This looks very cool.

Awesome! Is the code from GSoC 2007 used, or is it completely new?
Wow!! Time to start taking full advantages from our videocard!
GLSL! we will be making a nice blogpost about this and other features and how we use it in the game, once a couple of fixes are done.
there are many more interesting things that are working really good now besides normal map preview, will review that in our blogpost too.
Cool!
An interesting use, for me, would be to edit & view normal maps in real-time for very high detail work in sculpting. Lots of little creases, etc, would be much better handled as normal maps, but creating them atm would be pretty annoying.
actually the normalmap thingy was mainly asked for editing, so they are working on that, once 2.46 is released we will have all the time from the developers to play with! 
however, i tried with 4k+ maps and it works like a charm right now 
you can see every little detail, but yes the main idea of this normalmap thing is to make them editable within blender.
Sweet! Looking forward to it. 
Does that mean like painting over the mesh with a sculpt like brush but instead of altering the mesh the drawn creases get applied to a normal map texture or bump map texture in reatime?
Edit:
oogsnoepje, AFAIK only some of the glsls-shaders are used from the gsoc project the rest is a rewrite.
Good grief! I think Blender is on steroids, judging by the growth rate! Can we even really imagine what Blender will be like in just two short years. Think about where it was two years ago. The development rate is stunning. The coding community is truly on a mission.
Score Sounds great. I’m impressed it works with huge textures [not that I expected it wouldn’t, but you get what I mean]
Terrific
Blender needs much better realtime preview of materials and shaders.
I hope this one will work out.

Meh!
Have compiled the branch but can’t get it to recognize any of the lights 
It does display the bumpmap but in a Solid-shaded way -.-
But anywho nizzle work <3
Great job on those things, Apricot is bringing quite a bit of cool stuff to Blender.
