I just came across this post titled "DIY paper Tux" by Geri (Gary) Druckman.
Unfortunately the image he provided in this post was in very low .jpg resolution (for printing that is), so I converted it to vector using http://vectormagic.com/ (which is fantistic!). The numbers are a little hard to read, but you can always use the original .jpg as reference. Grab the .SVG version here: http://madsrh.googlepages.com/linux_paper_model.svg
Just print it out, cut it out, glue following the numbers and VOILA! You have your own hand made cute as a button Tux!
