This is only a graphic design for the concept of a Minecraft Mob creator. What you see above is not a picture of an actual application.
Original Minecraft Forum thread:www.minecraftforum.net/topic/12331-mc-mob-maker/page__view__findpost__p__1342766
3D preview window done in Blender
Menu element designs by me
Minecraft textures belong to Mojang
This whole thing has taken me at least 7 hours work.
I am finished with this design. Any mod/application developers may use it as they wish for their projects.
