I discovered "kryptonite candy". It glows green. Although this is not bioluminescence, phosphorescence is certainly similar. And it's on instructables, so we can all make it!
There are also apparently silkworms that spin colored, flourescent silk. Essentially, scientists (the fact that it's scientists makes it okay. Brings up the issues of ethics with bioluminescence) have been feeding silkworms a mulberry mixture with flourescent dye.
