Online katakana dictionary!

I have a katakana dictionary in book form, but I couldn't find a word in it, so I looked online to do the usual "what does this word mean in context" thing, and came upon an online katakana dictionary created by a Japanese guy named Yamada Yosuke (or, in the English version of the name, Yosuke Yamada, since Yamada is his last name). At least that was the name I saw after the Japanese word for "publisher".

What is really great is that he gives you the katakana word, the English meaning, then an example in Japanese! I hope he never takes this site down!
