Hi Shaz, as Geeg has already said Backscratchers are the original and imo still the best. I used their system when it first came over from the states too many years ago to want to remember! They have excellent training and great customer service. I know it's considered to be a little outdated but I just love the look and feel of fibreglass enhancements! For me shellac has taken over and I only do the very odd set of fibreglass nails now and tend to use it mainly for repairs.
As for art, you can use the resin like a glue to attach gems, glitter and premade acrylic pretties! I'm not sure if you could do rockstar style nails with the glitter embedded though. >>>>>>> goes off to have a play
