We got them on Amazon: http://www.amazon.com/Accoutrements-12305-Giant-Googly-Eyes/dp/B008BGP9KQ/
Not sure these are the right ones, just an example: http://www.amazon.com/Accoutrements-12305-Giant-Googly-Eyes/dp/B008BGP9KQ/ref=sr_1_16?ie=UTF8&qid=1445032274&sr=8-16&keywords=googly+eyes
I can't actually take credit for the gif, sadly. ...I would love to have a miata.
These ones on amazon are self adhesive. I don't know if they're what are used in the gif though: http://www.amazon.com/Accoutrements-12305-Giant-Googly-Eyes/dp/B008BGP9KQ/ref=sr_1_16?ie=UTF8&qid=1445032274&sr=8-16&keywords=googly+eyes
