I find this App Concept so wonderful BUT unfortunately it seems that its creator, Jonas Eriksson, a native of Sweden and an award winning interactive designer and developer, has not yet found any developer willing to help him make it a real product.
I am so sad that I do not have the skills required! Please also check his website featuring other great designs.
T’is a four star rated product on the Apple store since late October 2011. Gorgeous looking with a great sound to match. Check it out —
