I find my eye banging (yes, banging) back and forth between the square and the name.

To be completely honest there isn't much about the design that I do like. The unspaced name makes it read more like "inversiong raphics". The inverted text in the square makes it look like the split words should spell something else, but they don't. The name Inversion Graphics is pretty long, but there is no break in the flow. It turns into one big tongue twister.

I think you can start over and get a much clearer, more defining logo. If I didn't think you could do it, i wouldn't bother commenting.
