Design by Humans are having a very interesting contest at the moment. For those who don’t know, Design by Humans is a fairly new but very cool ongoing t-shirt competition. But this contest is not for the t-shirt designers but for anybody. If you have good marketing skills you can do very well. Let’s put aside the fact that Design by Humans is practically encouraging you to spam your friends and take a look at the prizes which are pretty sweet.

The top 5 humans with the most used referral codes (ie. most orders placed with your referral code) will win amazing prizes from Apple and Design by Humans.

1st Place
* 15″ inch Macbook Pro  2.4 GHZ ($1,999 value)
* The new 8Gig iPhone 3G* ($199 value)
* $50 DBH Dollars
* All of your friends who use your referral code will also receive a $10 iTunes Gift Card, and will love you forever (Yes, if 1,000 of your friends use your referral code, DBH will be awarding $10,000 in iTunes to your friends).

2nd Place
* The new 8Gig iPhone 3G* ($199 value)
* $50 DBH Dollars

3rd Place
* The new 8Gig iPhone 3G* ($199 value)
* $50 DBH Dollars

4th Place
* The new 8Gig iPhone 3G* ($199 value)
* $50 DBH Dollars

5th Place
* The new 8Gig iPhone 3G* ($199 value)
* $50 DBH Dollars

*(service and activation not included on iPhone 3g)

The Design By Humans Friend-A-Thon Contest expires at midnight on July 6, 2008 California time.

If I wanted to win one of these prizes I have to get as many people to use my referral code (deadhippo) as I can but I don’t want to spam my friends and I’m pretty sure I don’t have enough readers to pull it off. On the other hand, our friends over at TRound Up might. And they are also giving away some free shirts themselves.
