I do really appreciate what OrigamiUSA has done for this digital diagram store channel. All of the people involved deserve our big kudos.
As one of the designers, I do feel the need to express my opinion about this topic. Although the store model is similar to the current iTune/Amazon online music store. the content material and market has huge differences. The diagram is the instruction of folding a model, not a folded model or implemented art piece by particular artist. The better analogy to music is the music score/script, not a song or performance. What is the market of selling music script? Can an origami artist provide a folded piece for sale on the store? It will be another topic of copyright and royalties. If you consider hourly rate and labor of efforts seriously, most of the prices are low and unjustified (IMHO). The profit can only compensate part of the labor and time for most of the cases. It is sill nothing compare to the passion the designer (or author) like to share. I haven't upload anything for sale yet. It would be great to see the origami sharing go to a more positive, appreciative, and inspiring direction. Happy Folding! Sy Chen
