With the intention of helping students to learn spectroscopy, an open access online game has been developed. It is presently in beta-form but already has 100s of spectra, mostly NMR, to challenge and stimulate.
The game is described in the following blog posts
http://usefulchem.blogspot.com/2009/02/web-based-spectra-game.html and http://www.chemspider.com/blog/the-spectral-game-as-an-educational-tool.

The game can be found at this url for the time being:
http://lxsrv7.oru.edu/~alang/ and there is a prize now announced:

ChemSpider is looking for additional spectral data to be added to the game. The data must be "Open Data". The spectral data will be deposited to ChemSpider for hosting and the spectral game will draw on both the structures and the spectra from ChemSpider in order to run.
