Groovy Hex Editor is a tool for editing binary formats. I've paid particular attention to making it colorful and easy to use and tried to give it a cool looking color scheme (hence the name "groovy" hex editor).

It's a fully functional hex editor with many advanced features. You can toggle the display between hex and decimal, and there is a built in inspector that easily lets you see the hex, decimal, and binary equivalents of a group of bytes at once.

You can easily control the number of bytes displayed per line, and the number of bytes per group. This make is excellent for viewing various data types (bytes, words, long words, etc).

Limitations:
