Another idea to stimulate interest might be ....
... People generate ideas - both just before the BASH and during the BASH - of pens they would like to see ....
For example, a pen made with no external metal parts. . Or a pen having a segmented barrel, but excluding any wood.
Just a thought .... such ideas, of course, could come all year round. . There could even be a forum dedicated to the posting of such ideas .... just a collection of incomplete ideas that people think of but don't have time to implement or fully develop themselves. . There is always some creative person out there who might be interested in putting some unusual concepts together and coming up with something novel, once they get the right stimulus.
