I have seen months ago a sketch with tiny bear like haribo candy ( http://www.google.fr/imgres?q=haribo+ours&hl=fr&sa=X&biw=1920&bih=971&tbm=isch&prmd=imvns&tbnid=iG3LEP7LlY8pOM:&imgrefurl=http://aupaysdenounours.com/blog/tag/ours-dor-haribo/&docid=PQvlQxMIYEWqBM&imgurl=http://aupaysdenounours.com/blog/wp-content/uploads/2011/10/view186.jpg&w=260&h=260&ei=ii7JTom8FsHa4QSz6-g9&zoom=1&iact=hc&vpx=279&vpy=175&dur=459&hovh=141&hovw=141&tx=103&ty=88&sig=109447595142284644750&page=1&tbnh=112&tbnw=112&start=0&ndsp=74&ved=1t:429,r:1,s:0)

They were falling out, and they have a mesh structure. 

I was thinking that it was an example of a library i have got but after 3 hours looking in each of my file i didn't manage to put my hand on. 

So you have an idea, please let me know !!

Thanks
