Did you make the anime girl? If not, I'm pretty sure there's a script-fu that makes a gradient look all motion blurred but like that.

Nah I didn't. I just found it on the internet. I used a whole heap of motion blur, and added some colour and a light source.

Ehh something with me and SNSD. Here's Yuri. I tried creating flow like Surf suggested. I gotta be honest though, I'm not completely happy with this yet.
