Steemitjam logo competition - 10 SBD + 5 SBD

Make a logo for the #steemitjam!

Steemitjam?

Steemitjam is a game jam started by @loomy. Game jams are a concentrated few days of game development, you can read the rules of the steemitjam. Another very famous game jam is Ludum Dare.

Logo

The steemitjam really needs a nice logo to catch the eye and show some seriousness. Here is where you come in!
I'm looking for a fairly simple logo that can be used for steemitjam announcement posts, and also the avatar for this account.
It would be good if you could create a version that allows adding a number at the bottom, SteemitJam #2 for example. But it's fine if not, adding text is within my capabilities.
To enter the competition simply make a post with your entry before this post pops (7 days), add the tag #steemitjam, and reply to this post with your entry.

Prize

I'll be giving out 10 SBD from @poet's account to my favourite entry. I also have an additional 5 SBD if I really like the winner, or I feel a second place is also deserving of a reward. That's the minimum. I may decide to add more.

Good luck!
