Nevermind – figured it out – I was using an image that had glasses, and the eyepieces of the glasses were transparent. I made them white/opaque (like the elephant’s eyes) so that the new render is on top of the “old eyes”, thus hiding them. Thanks again for sharing the script!

Awesome script – thank you for sharing! I’ve got it working, for the most part, but mine seems to keep duplicating the eyes on movement (I am using a different png with transparent background). I understand that with canvas there is no “erase” method, as you are simply drawing the pixels in, but how did you achieve the movement effect without showing the “duplicates” that are rendered? Is there a background or fillrect that is covering up the “old eyes” that I am missing somewhere?

I imagine that’s not possible

How to achieve this effect using only HTML5 tags without javascript?

Your smoke effect is fucking awesome! I used it for my Breaking Bad CodePen. Thank you!

Hi Ed, thanks for the reply. I got it working http://jsfiddle.net/zE67k/1/ incase anyone wants to know. I just don’t know how to swap out the eyes for my own image.

I don’t know. Have you tried debugging with firebug? Check what’s happening with the x and y co-ord of each eye
