I am trying to create a "flip" effect for images, so that, on click, you rotate the image to 90 degrees along the y axis, change the image, and rotate it back, so that it looks like it flips around to reveal a new image.
The problem: There is a delay when switching the image in Firefox. It works fine in Safari and Chrome.
This delay happens even while it is uploaded on a proper web server, using the .htaccess file here: https://gist.github.com/themorgantown/4758846
Here is a small demo of the issue: http://oanagoge.com/TempHidden/FlipBug/FlipBug.html (warning: contains cute cat)
And the Hype source: http://1drv.ms/1hHAgFW
Any ideas what may be causing this and how I can fix it? Thanks.
