Sorry Soma, it doesn't look like I'll have the time to start it, let alone finish it. The best I could do is share some ideas if someone else can do it. Anyone is welcome to take these ideas, or modify it, if you'd like.
For the Channel Icon:
I was planning on pretty much doing exactly what soma said in the original post. Super cartoony, probably just a circle as the head.
For the Channel Banner:
I was going to do the "SpoonZ" name in some font that I would have made (probably something resembling bubble letters). The two "O's" in "Spoon" would have been a blue and orange portal from the portals game. The "Z" would have been bold or at least something different than the other letters. Could have been made of mossy cobblestone blocks (cartoony), or could make the "P" out of brick blocks. Not sure what I would have done with the "S," though.
