Hi everyone,

After some discussions in the fluid-work IRC channel and with colleagues at
the IDRC office, I will be coming up with a new design for the keyboard
plugin. As interesting and novel as a matching game (or any game) would be,
it may introduce unnecessary complexity to a demo whose purpose is to
clearly convey what is being demonstrated and how it can be used.

The new design I am working on now is an image gallery viewer - there is a
large viewing area and below that a filmstrip containing image thumbnails.
The user can use the keyboard plugin to navigate to the thumbnail strip,
choose an image to view, then navigate back to the main viewer and rank the

I hope to have this new design out by this afternoon EST.

- Jonathan.
