Barely 5 min into his opening keynote speech at NIWeek, Tim Dehne paused to ask how many attendees had all 10 of the T-shirts given away at past conferences. A few hands went up. Dehne, NI's senior vice president of R&D, even found one attendee who was wearing the first one, which gives the top-10 reasons for attending NIWeek. Though rumors of the T-shirts going up for auction on eBay abound, they have in reality become collectors' items that are truly priceless—since no one seems to have heard of anyone actually paying for a vintage shirt. "It's more a badge of honor that you've been here for years," says Kyle Voosen, vision product manager at NI. In addition to T-shirts, this year's attendees also got small badges with a blank space for proud wearers to enter the version of LabView that they started with. Co-founder Jeff Kodosky bested everyone, putting Version 0.0 on his badge. Go to http://rbi.ims.ca/3855-548 to view the full collection (almost) of NIWeek T-shirts.
