Nice work, Ron! As someone that speaks at conferences, I would appreciate this as a gift for speaking. Many times, the only gift for speaking is free entry to the conference (which is a double-edged sword, because most of your time "attending" the conference is spent answering questions in the hallway both before and after your talk; so rarely do you ever get to attend as a regular attendee, e.g. to sit-in on talks from colleagues)
