I do have it working, interesting that Safari changes some of the folder structure names when I view it online, looking at the errors I could see what needed to be changed.
Learned a lot in 10 min. looking at the code - so perfect, reads like a song (when I look at my code it is more like the sound of a train crash vice a song) 
PS. it would be very helpful (at least for me) to have zips of the showcases somehow available for download - learning is better / quicker when I can mess with something that works and is done correctly…
