Richard Macmanus offers a rundown of the 13 startups profiled at the Web 2.0 Summit's Launchpad. They range from mashup music games to sticky notes to a 3D social network.

Here are a few of the ones Richard liked best:

• Sharpcast, - "It synchs data across PCs, the Web and mobile. Sharpcast Photos was the first such product, but today Gibu Thomas the CEO is launching a product code-named Hummingbird - which synchs all files."
  
  

• Stikkit - Created by former O'Reilly resident geek Rael Dornfest (wonder how he got a slot), Stikkit "makes messy data smarter and allows you to share that data. So it's a very granular data-sharing app."
  
  

• 3B - a 3D social network that requires no extra software. "You can use MySpace, Hi5 or Bebo pages or photos you've loaded onto Flickr, Photobucket or any other web service. ... It's also a visual search tool, allowing you to order search windows in the 3D space. You can change the wallpaper and create 'personal 3D spaces.' It looks like it uses scraping to put other web content inside this 3D environment. "
