This is page which I made some time ago. Unfortunatly English version isn't avaliable yet, but there are some animations and images so i think page is worth seeing.
There some menu translations:
"tworzenie" Prosty silnik - article with a lot of images and photos. It is about how to make simple Stirling engine. Ko=B3o zamachowe - article about making wheel(?)
"galerie silnik=F3w" - it means engines gallery, a lot of high quality photos of engines
You can also see "historia" (history), where is nice animation of first Stirling engine bulit in 18th century.
