SCoTT's first attempts at using the GIMP.

Echidna logo with an unknown spectra I found on google/images.

I used a solar spectra from the NOAO for this one.

Dionne pointed me to a composite image of 20,000 spectra from the 2dF quasar survey.

Jacinta snapped this zippy fellow on our bicycle ride around Dubbo Zoo. The photograph is on my office wall.

Black emphasises the background glare, but I haven't found a nice way of representing the silhoutted Echidna.
