I for one do a lot ao single-layer fractals. Mainly because I'm really new to fractals. At the same time I do love to experiment, just starting with flames now and hoping to work my way to layering. In the day and age that we live in now, with everything in a constant state of change, who's to say what is traditional and what is not? What is non-traditional at this point, may within the next year or so, be considered traditional! Just enjoy what you do. Do art for art's sake! No more, no less!
