#2 is interesting but I would love for there to be some symbolism involving games or education. Not sure how I feel about apples. The font for #5 is pretty good. Why does the apple look wavy on the upper right?
The apple is an education symbol. In addition it is an universal symbol of desire. It is beten off in order to involve commitment to these ideas. And - you know, the infineshed items always are most remarcable.
