It sure is a brave new world today.
In the old days, if you wanted to look up the meaning of a Japanese word, you had plod through a paper dictionary.
But no more.
Now, not only are there online dictionaries like Goo, but there's even the super-fast dictionary Nihongodict.com: Type in an English or Japanese word, and its other-language equivalent appears almost instantaneously.
Another cool resource: clickable kanji lookup by radical at Denshi Jisho (Electronic Dictionary).
This has nothing to do with learning Japanese. Instead, it's just a mellow photograph of a circumhorizon arc, also known as a summertime halo.
