Sweet potato latex

Here’s a fun trick for Thanksgiving. If you get into an argument about whether you purchased yams or sweet potatoes at the store, chop one in half before cooking and look for milky white sap bleeding off the flesh. Only sweet potatoes do that. But if you don’t see sap, that might mean you just have an old sweet potato, so don’t place large bets when doing this. More useless trivia at “Yams versus sweet potatoes“.

Fabric conference posters

I was invited to talk about poster design in Berkeley (DOE NNSA SSGF) and DC (DOE CSGF) this past summer, and used the opportunity to test out fabric as a medium for large-format conference posters. Below are some photographs if you’re curious how logos, illustrations, and photographs look when viewed close up on fabric. By the way, I ordered the posters from PhD Posters (they mailed to my house in a tube, inside a box). And if you’re interested, my poster design tips are here (rather long-winded because I’ve maintained page since 1997).

The rolled up poster above is also fabric. I didn’t have the nerve to fold it into luggage-sized square, but I’ve heard that it can be done … though crease lines an issue. Might be able to iron them out, I’ve also read.

The photograph above isn’t as crisp as a glossy poster, but was totally fine for my purposes. If it really mattered, I’d just print a copy on my photo printer at 1200 dpi (or whatever) and then use double sided tape to attach. Even paper posters have fairly low photo quality, so attaching a high-resolution version is always an option when you need it.

Yes, you can see the fabric if you get close enough. People standing 6 feet away wouldn’t notice and probably wouldn’t care if you told them.

This logo is actually from the poster that is rolled up. It’s at https://colinpurrington.com/2012/example-of-bad-scientific-poster/ if you want to see the whole poster (you can download and print for your class, if you’d like; yeah, students would just love that).

fabric-poster-edge-detailThis photograph shows how the edges can get a little frayed. Holes from pushpins are also visible. Much less annoying than the rips and gaping holes that paper gets.
