Wapuloader for Contact Form 7 is a really simple WordPress plugin that does nothing practical apart from replacing Contact Form 7's spinner icon, which appears when you click the submit button, with a rolling Wapuu image.
Note: Wapuloader works with Contact Form 7 version 5.6 or higher. Also, this plugin uses SVG and CSS animation, which are not that cutting-edge technologies, but might not work on outdated browsers. Please do not expect any practical functionality from this plugin.
