Holographic lighting in Cycles

Question

Is it possible to create a holographic lighting in cycles? This is possible In the Blender Internal render engine, but I'm not going for linking lamps. Here is what I mean (the light that is holding the sphere inside it) -

Yes, this is possible using volumetrics:

Method 1:

Using a cube to scatter light emitted from a spot lamp.

Create a cube and give it a volume scatter material:
Add a spot lamp:

Method 2:

You could also fake this by modeling the cone, then using a volumetric gradient for the falloff:

It won't be as physically accurate or as flexible, but it will be less noisy:

Example .blend (for both methods)

Thanks. is the light source a "sun lamp"? – Vladimir Sep 16 '14 at 21:59
@Vladimir No, a sun lamp wouldn't work for this at all.. – gandalf3 Sep 16 '14 at 22:07
Would you like to post a blend? 'Cause the volume is showing the shape of the cube and its nothing like your image above. – Vladimir Sep 16 '14 at 22:25
