Via @justinvincent I found Mindmeister – a supercool mind mapping collaboration tool!

This suits me perfectly for the game project I mentioned in my last post.

It supports embedding, too! Unfortunately, refuses to accept the HTML-code for it  – but embedding looks like this (proof-of-concept on my own testing-server). The direct link for the mind map I’m making for the game project can be found here. Really neat tool!

In fact, I like it so much that I feel prepared to pay for premium once I turn 18. I haven’t looked into the difference of Free and Premium though, and I haven’t seen the price tag either, so I’m assuming it’s realistic.
