Broken Glass Logo

We need a logo that reflects broken glass and one that is super simple with few fine lines and not too much detail. Attached are some sketches from our team to reflect what we are aiming for. Some of the key elements are that we would like are a horizontal line in it somehow to represent a ceiling. The glass shards, perhaps, to break the glass. We are going for simple black, solid. Again, a logo with simplicity that has a "less is more" concept is perfect. It can be very very basic. One thing that we didn't sketch but considered afterward is a black square with a broken hole in it ... or a black square or shape that forms the letter G around the broken glass (see the vector sample attached from vectorstock that has broken glass ... it does not form a letter, but the concept caught our eye by creating the letter G in it ... again, simple black though). Thanks for taking a look!
