Nice HTML5-based Online Modeling Tool

Looks nice, but the constant floating around and 'wiggling' really bugged me. It took me quite a while to figure out how to add and remove things.<p>It also reminded me of an ORM tool which I helped build in college called nORMa. It was a plugin for Visual Studio and was great for designing complex databases.<p><a href="http://www.objectrolemodeling.com/AboutORM/ORMTools/NORMA/tabid/87/Default.aspx" rel="nofollow">http://www.objectrolemodeling.com/AboutORM/ORMTools/NORMA/ta...</a>

The fluid movement + ghosting is well done. There are the beginnings of a pleasant interface here.<p>One issue: I couldn't figure out how to connect two nodes to make loops. Adding and deleting worked just find-- but not connecting existing elements.
