An mouse effect that you can easily add to your files. Just drag&drop a mc to your file and it will be ready. I saw something like that on a site and first made it with only lineTo method. That was prety rought and here is new one with curves.
There are many things that you can edit. Size of blur, thickness, color, length of line etc also you can disable rainbow mode, so your line will have a constant color. Also you can add other filters easily, just add any filter to mouseeffect mc and it will also apply to line.
Here are my current files a preloader with as3 (so you will need cs3 in order to use this)
You can change bottle, particles easily. You can set the where shoud particles come, their speed, number, friction etc
Check my other files if you like this one! Thanks.
