I found this test on Youtube, I wonder is it Maya Or Houdini? Because I try to create some Particles FX like this in maya, but may it be impossible.

You can do something similar to this using Maya hardware render buffer and many samples. This smears the particles over time in a similar way to motion blur.
You can also do stuff like that using xparticles in Cinema 4d.
