Really cool widget, but to me your tagline seems wrong. You give away tshirts at conferences because people notice them, they don't notice socks. Just say, make cool socks.
You receive points for an objectively correct answer.
I would definitely remember the company giving out wacky socks, especially if they were wearable (in terms of material quality).
I'm not saying novelty socks can't happen, and certainly there are a few fashion labels making a pretty good buck off of socks with fun, quirky, and unique designs. That's sort of an emerging space in the apparel business, actually. But the use case is somewhat different from the novelty t-shirt market.
