L'actu par Mac4Ever (fr) made a call for developer to develop some completely useless software for MacOS X: a screen saver intended to be as a demo. Aren't there more urgent things to do like helping AbiWord native Cocoa port to be more polished or help porting gtk+ to MacOS X without X11 so that one can port Gnumeric that is IMHO a real jewel. Most of the time, the excuse to not take part of these projects in the MacOS community is because they like making shareware and need to pay the bill.
We, the AbiWord team, have been looking for a long time for help from developers in the Mac community, without much success.
