Its not the most beautiful thing but it exists. Maybe someone with zbrush can turn the numbers into a brainy mesh too. might be cool.
I saw the brain cube and thought that it would look cool as a dice. but since that wasnt available i made a dice font in Magicavoxel (looks cuby but is the easyest and fastest tool around) and combined the two in blender. Easy as brain.
For any interested, ill upload the dice font so you can turn anything in a dice too with blender
