That's right! 2011 marks the 20th anniversary of when Nicktoons first started airing! This is just a little idea I came up with a while back to celebrate it. I was sort of inspired by the logos SpongeBob and The Simpsons made to celebrate their recent anniversaries, where they used character bits and silhouettes to make numbers and words.
Feel free to use this logo in any celebratory piece of art you make for the anniversary. Just make sure to credit me if you do.
EDIT: Some people say that the SpongeBob eye as the 0 doesn't work too well the way it is. Taking their suggestions, I made it more clear to see that it's SpongeBob's eye. If you don't like it, blame the the guys who suggested it. ...No, just kidding. Don't do that.
