What's That Stuff? tells you the chemical composition of everday things. Also Visual Recipes, including some chocolate foods like this Chocolate Chip Cinnamon Swirl Ice Cream. This site has 125 recipes and might be more useful if the photos looked more appetizing. And for the dexterity-challenged among us (Me! Me!), How to Flip a Pen. Found on Idle Type.
From a reference phone call today. I'll just give my side, partially paraphrased:
"Yes, we have books on learning braille. They're print books and are reference only. Yes, you can make photocopies. They have the braille printed as black dots."
"Yes, we have the Bible in braille. Mostly, we have reference copies. No, you can't make photocopies. Braille is just raised bumps. If you try photocopying that, you'll get blank pages. Well, maybe with some tiny shadows."
This took me a few minutes to explain, along with the added complications that someone needs good sensitivity in their fingers to read braille and it's not just letter for letter, but a lot of contractions that a potential braille reader needs to learn. It can take years of study. I'm not sure the woman really grasped what I was saying.
