What was this online dictionary's name with ancient traditional and simplified characters and glyph origins?
On http://ctext.org/dictionary.pl?if=en you can see how a character evolved, the simplified and traditional characters. For example for 目.

Another similar website is http://www.chineseetymology.org/CharacterEtymology.aspx . Their result for 目.

Zdict is completely in Chinese: http://www.zdic.net/zd/zi/ZdicE7Zdic9BZdicAE.htm

Here is another website in Chinese (that only supports transitional characters): http://alphads10-2.hkbu.edu.hk/~lcprichi/

As Aristide mentioned http://www.yellowbridge.com has similar functionality.

Another one is http://chinese-characters.org/

Although it doesn't show how the characters evolved, I also like http://zhongwen.com
