I wan't to wiggle an existing path - in the style og the blobs here:  , but this one creates blobs instead of using an existing.   In this previous post there are some discussion on the topic:      I have tried Jack's waveSVG that accepts existing path data. But I notice the start and end points aren't aligning in the wave motion. I will only wiggle a blob consisting of around 20 points. The various blobs are used as backgrounds for line icons.     Thanks
