Little Packs o' Art
For some, it's a complete waste of time. For others, it's a wonderful array of interesting packaging (I'll leave that debate up to you). Check out Museum of Condiment Packets.
Just about all your favorite condiment packets are there (soy, mayo, hot sauce, etc.). It's interesting how some more creative designers have tried their best, but most just stick to a certain formula (yellow for mustard, red for ketchup).
Personally, I like a lot of copy on my packets. Don't know why, but sometimes eating fast food can be terribly boring and a gal just needs somethin' interesting to read.
