I like it! I started making a similar kind of page before as a brainstorming challenge: "noun is like a noun".

2 people could sit in front of the screen, and the first person to guess how the nouns are similar would win the point.

I'd also like to make a pun dictionary of similar-sounding words in English & Chinese, using the data I already gathered for Pingtype.
