When using OmniDiskSweeper, or any utility that shows all your files... See the following article if you want to run it as root

Boiler Plate Warnings:
DO NOT delete files in your Home Folder -> Library tree as there are things like your iPhone backups, your email messages, your application preferences, etc… If you think you have found something in your Home Folder -> Library that can be deleted, you should ask first.
DO NOT delete files outside your home folder, as you may end up deleting something essential to Mac OS X, and turn your Mac into an expensive “Door Stop”.
I will point out that you will find some very large files in private -> var -> vm (these are the Mac OS X virtual memory paging files (swapfiles) and where Mac OS X stores the copy of RAM when your Mac is put to sleep). The swapfiles get deleted on reboot, and the sleep image is just going to be created again when you put your Mac to sleep.
If you think you have found something to delete outside your home folder, it would be best to ask first before deleting. There are many examples of people deleting files outside their home folder, or renaming files, or changing the ownership or file permissions, and then their Mac stops running. Do not be one of those people. Ask first.
NOTE: 10.7 is Lion. Mountain Lion is 10.8
