Yesterday I released a Beta for the new TNT Primz..
Its a building tool very similar to the Skidz Primz.
Here is a Youtube Video

It has the kewlest new Texture mode. You can actually drag a texture around on the face of a prim. It also aligns your textures/sides rotations/edges/corners/so on

You can get a copy of the beta now at Skidz Isle. Near the Skidz Primz display.
