that's amazing, I have seen pictures of this bird in today's news paper.

Nice that you have posted videos of this.

That's amazing about it. The bird which looks so simple is very complex, and has taken many many years of R&D.

What was that???

Can you imagine it's applications? It is mind boggling.
