5 and 11 are my favorites. The L4 on half of Logo 10 would make a great shirt icon. Any other configurations for the number 4 in the name. I envision it as "lite to the 4th power", like math class. The 4 would be raised up higher (much like me old logo).
These are still the best so far but I was hoping for a bit more cool graphic styling and fresh look when I entered the contest. I may have moved the 'simple bar too far to the left'
I really like 47 the best of all the ones you have done. This is going to be a very hard one to decide. It looks very "fast" and clean, almost like something you would see on a racecar :-) Thank you for the hard work and all the variations. I am very pleased with where it has ended up.
I don't think I would change anything, I think you did an excellent job. I just have to decide which "feel" we are going to go with. Thank you for all the hard work. Now to decide.
