A really nicely put together tool!
The use of a "ring buffer" to display the generated names was a really nice way of balancing the ability to look at previous generated names while not being potentially overwhelming like a list box of the complete history might be.
I could also see this tool potentially being useful for designers/developers too when creating mock-ups or documentation. Could be cool to have an option to render the names into pre-made "chat message", "game lobby" and/or "social media" template images too.
FROSTCHEF signing off! :D
