Thanks, Danbou.
Rich: Yes, it seems to be something glowy going on there. I'm not an expert in render methods, so I guess the reason why the first one does not have this glow must be what Fletch said: It's actually caustics coming from the point light. Since the first one was done with regular MLT, it only casts rays from the camera, and not from the light sources; since I had a point light behind the cube, there's no way on Earth enough rays are going to hit exactly that point. But if I had used an emitter, then some rays will hit the surface and perhaps I could have seen the same effect. The second one, Bi-directional MLT, casts rays from both the camera and the light sources, that's why it has no trouble rendering these special FX.
Bottom line: Easy 09 is cool. Easy 10 is awesome.
Then again, I'm no expert, so take this with a grain of salt. No, make it a cupful of salt.
Two more from the same "Render this" thread.
For this one, I only changed the sky to "sky color", and set it to white. Material is the blue gum from the library, and exposure was raised a lot.

For this one, I placed two emitters: A light blue one to the right and a yellowish one to the left. There's no sun or sky. I used settings similar to the ones I posted here:

I also did the following in GIMP:
-Added some white airbrush around the eyes
-Lowered the Blue channel curve to make it warmer
-Raised the "All channels" curve.
