My suggestion is we need not have a nice caption, we should also think about some good design (like writing in special fonts, lots of equations etc.). tat will make up if the caption is not so good.
suggestions-
1) iCame iSaw iApplied (but tat would be kind of cliched)
2) I 'AM' what I 'AM' (for those who dont know tats actually tats a famous reebok tee caption)
