I was searching for cartoons about icefish, the topic of next Monday's lectures, when I came across this site http://www.radiantcompany.com/system/overview.shtml . It's about radiant floor heating systems, something we are considering for the house. And it has an Antarctic (penguin) icefishing.
(BTW, the icefish are really interesting because they have lost hemoglobin, something most vertebrates can't live without. The cold oxygen-saturated water in Antarctica allows them to survive without it).
