FontLab produces TypeTool 2, a low-cost font-editing program. I've long been fascinated by typography (I still have the printer's type specimen book my mother used briefly at the Village Voice, with my red crayon scrawls in it). TypeTool seems to be a solid if not luxurious font editor. If I only had the time (and inspiration and artisitic ability!) I would try my hand at it. Let a thousand faces bloom!
