I don't think I ever posted this:

http://pastie.org/9456438

It's a small Python script that takes any number of BTC, LTC, DOGE, and CLAM addresses and gives links to the corresponding blockchain explorer pages for the equivalent BTC, LTC, DOGE, and CLAM addresses.

When there was a giant influx of newly dug CLAMs about a week ago, I ran this script on a bunch of the CLAM addresses that were staking, and discovered that the new CLAMs were being dug from DOGE addresses.

Here's an example of it in use:

$ ./clam.py 18KSgPcNRPi9K4bp91Vb3pVNygPon4y5Pw x9S2gMQQ5iKrP9SwRJ6PF9Q3wqDxRegc2w

   BTC: http://blockchain.info/address/18KSgPcNRPi9K4bp91Vb3pVNygPon4y5Pw
  DOGE: http://dogechain.info/address/DCTYDeZ1iocRr4nQsbV9baeyrp878jRzaG
   LTC: http://block-explorer.com/address/LSYPwbvCW3xCZsHyK9UtKqZ9Btm5wrJXxa
  CLAM: http://khashier.com:2750/address/xFd5aGSqh7CBMShgVV8FUznACnh3DALPss


   BTC: http://blockchain.info/address/128PnUZvozqpLmM54pTioy7Giivj44ketX
  DOGE: http://dogechain.info/address/D6GVKjWa7Qk6smXfoQTHMjGsbrf2Nvx5Po
   LTC: http://block-explorer.com/address/LLMM3gsktf5sba3EExT25zB2vwJ17S9JV2
  CLAM: http://khashier.com:2750/address/x9S2gMQQ5iKrP9SwRJ6PF9Q3wqDxRegc2w


It uses https://github.com/jgarzik/python-bitcoinlib.git to do the heavy lifting, so you'll need to fetch that using git, and update the path to it in the script itself.

Edit: I forgot to say why this is useful... If you only just heard about CLAMs, and are worried about sharing your Bitcoin wallet with the CLAM client, you can use this script to convert your BTC addresses to CLAM addresses and look up the balance on the CLAM address without needed to give anyone your private keys at all. Bear in mind that your wallet probably has a bunch of "change" addresses in it which it carefully hides from view, and those change addresses may have CLAMs on them too, so you probably have more CLAMs than you think...

Edit2: the two addresses I gave in the example aren't great. The first is a BTC address that wasn't funded for the initial CLAM distribution, and the second is a CLAM address that I created in the CLAM client. But you get the idea!
