¿Qué idea tienes, qué estilo te gusta para tu t-shirt?
Visual style should be rock'n'roll, but there is no need for much style redesign. The idea from the screenshot, about "rolling stones" style tongues with country flags, is what we want. It would seem that tongue viewed directly from front rather than from an angle works best, but we it is up to you to come up with something that looks great.
We need a complete re-work of the design which you can see on the attached screenshot: tongue with planet earth in the middle, surrounded by tongues with country flags. The shirt should also have the Transfluent logo small size somewhere.
Note that the design doesn't have to be exactly as in the screenshot, it can also be made better. Just the basic idea has to be the tongues with country flags.
Lo que debe evitarse
You may not use any graphical items from iStockPhoto, or any other image bank which prohibits using the licensed art for on-demand-printing. Also, don't use the screenshot directly (it is intentionally in very low resolution so you cannot copy - you need to create the image from scratch).
