::hugs:: I have been in that level of fail many many times. Scissors and ideas are normally pretty okay to throw across the room (as long as no living thing is in the way) but machines tend to leave holes in walls and you never find all those lil metal pieces....and then there is that burnt rubber + metal smell that never quite leaves your nostrils for a few days...

Work on something else. Even if it's something simple, just work on something else.
