I've been in search of a floating blue that works for me. I've tried about three variations of basically the same formula, and the most recent has produced the best results. However, it apparently crackles. (Ping!) Not visibly, but audibly. I wanted some opinions (and this is usually a great place to get them) about whether the crackle is likely a function of the movement that creates the floating effect? I suspect that if I put this formula into Insight and manipulate it to get rid of the crackle, I might also get rid of the 'float'. Any thoughts, anyone?
