Lucky?
Well this one here was very entertaining with this number you ussd, kept me wondering why you picked this number, and gave me a few smiles with the use of yellows and the outlines in the numbers and squiggles, and somewhat random squiggles at that but thats what i liked about it, so good job and keep it up.
