to help balance this out, you could always ask for a crafting skill check for any "complicated" shapes (aka the spheres, laticeworks ect..) This would still allow it to happen, but make it something that the caster would have to work at to get right.
You could require the character to make a spellcraft check to break the spell down smaller than 1 cubic foot sections.. set the DC based on how much you are reducing the base listed dimension.. assume DC 0 to cast the spell as stated.. in 1 cubic ft sections.. DC 10 to go with 10" sections, DC20 to go with 8" sections, DC 30 to go with 6" sections, DC 40 for 4" sections, DC 50 for 2" sections.. so only a near Epic caster has a remote chance of carving 2" wide sections affecting enourmous amounts of stone by using negative space...your average 10th level caster has about a +15 spellcraft... so cutting it into 6" sections is feasable, but a little difficult...
So what would you all say to touching a wall ( as the range IS touch ) and having a 1 ft. square with a point go shooting out of it at an opponent? Damage? DC should obviously by 10+spell level+ability mod. or what about holding your action until an opponent is in the doorway in front of you, then touching the walls to form arcing bands confining him there? ( a band running from the left wall arcing horizontally to the right wall, with the same running behind)
