The Space Egg Hunt from Coffee Cup Software is on and if you have not checked out http://www.coffeecup.com I highly recommend it.
Until the last egg is found – you have as good a chance as anyone to secure free goods, rewards or even a holiday in Spain. Literally – all you have to do is register as a user and start looking.
I will admit I found about 20 eggs *that were already redeemed) before I found mine. One click and I got a new user license for their best product.
For anyone looking (and maybe a little frustrated), below is a screenshot of one I found.
The eggs pop up in random locations. I saw them behind text and ranging in size from 15-50 px tall. They also range from 20%-100% opaque.
