To Brighten Your Sky

I'm working on a fun new project that I've been putting off for some time, and this wall is just basically a mistake/test...but I thought it turned out kind of ok, so I thought I'd test it on you guys....lol/

Yeah, sorry...it's rather bright....I couldn't use it as a wall, myself....but someone else may...though I doubt it.....

But more over...can you guess what my project is?
I'll give you another hint...
