[QUOTE=ewmayer;516936]Hey, George, here's an idea -- offer an autographed copy of one of your prime discovery papers to $100 donors.[/QUOTE]

I think that donors would prefer a t-shirt or poster with one of the Mersenne Primes printed on it. That does give me an idea. Someone could design a GIMPS t-shirt. The cost per t-shirt would likely be less than $5 per t-shirt, but could be sold for $15. I think that would get you a lot of donors.

Or with the word GIMPS on the breast pocket area and the rest on the back.

Bring out the GIMPS, a simplistic brushstroke style drawing of two guys facing to camera tied up with ball gags while some kind of Lovecraftian Mersenne monstrosity is unfurling behind them. The ball gags are a splash of red on an otherwise monochromatic design.

I actually like those. Not t-shirts, but something I could wear to work.

A t-shirt would be more casual and something to show off to people outside of work.

I agree. I still have mine and wear it often.

I would buy a polo or a t-shirt as well. Summer is approaching.

Summer? That nice weekend in July.

I still have a small handful of that big batch of logo polos I had made up ~15 years ago - the precise color/size list is on the [url=http://www.mersenneforum.org/mayer/README.html]Mlucas README page[/url]. I've been using them as carrots for Mlucas-related moneyraising, but I'll offer them here, free shirt for a donation of $100 or more to GIMPS. Mostly smaller sizes left, but if you can't find one to fit you, consider gifting one to the wife. The only thing I need to think about is cost of postage - no big deal within US, but would cost ~$15 per shirt to ship internationally. I suppose $100 donors could reimburse postage via separate paypal to me, but nah - I'll cover the postage as my small contribution to this year's fundraiser.

Perhaps in advance of next year's beg-a-thon we could have one of those professional-swag sites (e.g. 4imprint.com) make up a batch of similar for us. We'd have to compare pricing to the "manual method" I used for the above - bought a bunch of polos for ~$10 each on eBay, took to a local custom-embroidery outfit. (The latter proved more of an adventure than it should've been - the shop owner mis-rendered the printed logo I gave him as "mersene.org", ended up having to re-do the entire batch of ~50 polos.)
