If you're like me, you have a bunch of stuff in the fridge, but when you open it, you say, "There's nothing for dinner!" There's a website to help us! It's called SuperCook, and all you have to do is enter in all the stuff you have on hand, and then it will generate a list of recipes you can make right now! Of course, if all you have is ketchup and Diet Coke, you're out of luck, but even seemingly random ingredients can come together and make a yummy meal. If you sign up for a free account, it will remember your list of foods so all you have to do is update it (out of carrots, but bought oranges, etc.). According to the site, I can make almost 800 recipes right now, including Chicken Cacciatore, Asparagus Risotto, and Breakfast Tortilla Strata. Of course, all I did was boil some ravioli, but it's nice to know I have options.
Just One Club Card is a website for those of us with a multitude of plastic "loyalty" cards. All you do is enter the barcode numbers from the back of the cards and choose the store names from drop-down boxes. The site then generates a credit card-sized image with up to 8 barcodes on it, which you can print out and even laminate if you wish. Not only does it save room on your wallet or keychain, but it makes it much easier to find the card you need. Mine has Kroger, CVS, Food Lion, Borders, Lowes Foods, PetSmart, Hallmark, and Dick's Sporting Goods. You can also do library cards via the "Advanced" tool.
And finally, if you like kaleidoscopes, you will like Repper. You can do stuff with the images that result if you want, but I just think it's fun to play with.
