So web services and cobbling them together is all the rage on the Net these days. Here's my idea.

Input: a search term (specifically, the title of a song).

Output: an HTML file, a CSS file, and a little Javascript.

Algorithm:

1. Scrape a Baidu MP3 Search for the given song title to grab the URL of a recording of the song in MP3 format.
2. Scrape a Baidu Lyrics Search for the lyrics of the song.
3. For each line of the lyrics:
   1. Scrape my Chinese Tool to get the pinyin and English for the song lyrics.
   2. Ask Flickr for a picture that relates to the line of lyrics.
4. Generate an S5 Slide Show: embed an auto-play link to the MP3 file, one line of lyrics with superscript pinyin per slide, each slide with a Flickr image background.

Click as you sing along. Ta-dah, one-stop home karaoke!
