Neon?  
This is cute

I say we keep this one as a different version of the one you uploaded.

I uploaded >>741661. We can conclusively say that nightsplash13 is an art thief. This image should be removed.

Found it! At least something. Took some serious searches in my Ponibooru archives, Tineyeing and some more (Derpi’s reverse search does not find it). Tineye gave me 26 results, none which appear to be the original. Equestria Daily has indexed this in Februrary 2011 and there are at least two copies of it on DeviantArt, both later than that day. All “original” ones seem to point to various wallpaper sites. I don’t know who made this originally. If no one objects, I can upload the copy I have.
 
But this “nightsplash13” definitely isn’t the original artist.

I don’t know.judging by the quality of the rest of the art i found at his gallery, it doesn’t even look he made this.

Again I feel I’ve seen this before. Long, long ago, but the DA page says this was submitted less than an hour ago.
