We created a slider plugin Transition Slider with some fresh and unique WebGL visual effects. The inspiration was video editing seamless transitions like https://videohive.net/item/handy-seamless-transitions-pack-script/18967340
We also plan to add much more effects soon, like glitch, crossfade and advanced image filters.

I am looking for a feedback from Themeforest authors. Do you think this kind of slider would be a good addon to your themes?
