I propose a new tag: CG-challenges

This tag will contain 'things' (purposefully vague) that are difficult to accurately portray in a digital environment. Often times these challenges fall out of my range of expertise and such I find it inappropriate to tackle them myself. But, I understand that someone might have the exact skillset to attempt a specific challenge. 

Today while reading a post about The Future of Iteration Design I encountered this image from the post:

What struck me about this photo was the complexity of the position of the hand, and the precision of the action. I propose to someone to accurately pose a virtual hand in similar manners to each one of the photos. Attention should be paid to the way the skin and muscles react and interact with each object. 

This tag-set will develop over the coming months to contain other challenges that I encounter and (re)discover.
