For the Deaf People Association (Malta) I am currently creating 3D prints of all 30 characters in the Maltese Sign Language (LSM) alphabet. (http://www.deafmalta.com/maltese-sign-language-lsm.html)
These models are meant to help new sign language users.
Sculpted in Zbrush, rigged and posed in Blender. Hollowed out and detail added back in ZBrush.
This is still work in progress, more sign language poses will follow in future posts
