My 2nd design for your contest, new background a mix between decimal & roman numbers 1 color and variations of the same to make it much less loud, hope you like it. If you have any other idea you wish to see please tell me. :)
#43 background is interesting with the numbers and letters. Can you do that in blue, and add some search related commands like: " & + : combine that with the type face you did for #40 and the design will go to number one in ranking.
