Having been playing around with idea of a light trail for my neon splash page (though is a tad cheesy, so is my neon sign), I thought it would be quite easy to find code for it, like I had with <script src="snowstorm.js"></script> but is proving trickier than I thought. Closest I found was: https://codepen.io/MAW/pen/bpQjGY but a bit too clunky as I want it to fade smoothly, and on considering how involved a smooth transition may be, thought logically about a particle trail instead using uploaded gifs (ie. circles with transparent backgrounds) and that same day I came across the L’or coffee advert as a pop-up which has this interactive function following cursor (though is more like glitter and I want mine far more subtle & simpler). Anyone? This is a still of sort of effect I was after: http://www.freeimages.com/premium/vector-shooting-star-with-light-trail-1193609 but may be too complex to achieve for what it is, so a series of very small gifs could give similar effect. I am familiar with doing animation in Flash, but using code to animate objects following the cursor over an existing image is not my area!
