The great range of apps that we see hosted in Launchpad never ceases to amaze me. Take Bauble for example:

Bauble is a biodiversity collection manager. It is intended to be used by botanic gardens, herbaria, arboreta, etc. to manage their collection information. It is a open, free, cross-platform alternative to BG-Base and similiar software. It uses Python, GTK+ and SQLAlchemy.

Am I alone in finding that really, really cool?
