CollectionOfStuff
At least a million widgets and gadgets have been done in Spring. But alot of cool things are lost because the game vanished or the idea never made it into a public release. Many items from Monthly_Topic_Rotation are actually done or could be done.
It also annoyed me that there are often forum threads where somebody explains in detail how to do something but its just lost in spam. So here is a collection of random things.
Some of the stuff might be outdated or rough "proves of concept":
