Logo GFX

I know multiple of you do GFX and I'm not sure what one to go with so I'm starting this to give all a chance.

I'm looking for a logo to go with the group I'm part of.
The group name is 'Null Patrol'.

We want a logo that represents the symbol for NULL. (google: Null Symbol)
I'm looking for someone to custom re-draw/make that symbol
I'm offering 10$ for the one who posts the best logo.
Logo should look good on a light or dark background (you could design 2 to fit light or dark backgrounds) but they must have invisible background in the final product.
Don't forget the watermark.

Let me know what you think and if you're interested.
If you're not interested, let me know why too.
