Awesome! YES! You've already won a share of the bonus prize... and you can still win more:

BONUS CHALLENGE UNLOCKED!

That stone did actually get some googlyeyes of his own!

Now anyone can reply to this comment with a copy of the image and the eyes edited in digitally
_{(I know that's totally not allowed for the real contest, but for this bonus game we'll have to do it that way, you can't all travel here and put real eyes on that stone :P)}

I'll put a total of at least 10 SBI up for grabs (issued through @googlyeyes, paid for by myself) for all images with eyes added to the stone - also, the one who puts the eyes exactly where I did (will be revealed on my bloog soon-ish) or who finds an even better spot (according to my subjective judgement :P) will get a bigger share of the total SBI.

BONUS CHALLENGE COMPLETED!

6 SBI for @bucipuci, 4 for @rubberduckimom
