We have released shader effect #12 - Plasma. Please head over to our website to see the demo in action.
In case any one does ask, the shader zip file is absolutely free for the Scirra 2 community. If you want the zip file, just head over to our Patreon page, select to become a patron and choose "No Reward". You pay nothing - $0. Zip. Nada. And you get access to all our stuff put up on Patreon for free. But, really it's entirely up to you.
