Shrimp chips/prawn crackers

[contradictacat.livejournal.com]

Does anyone know where I can find shrimp chips of the type that may come with certain Chinese dishes- round, very fluffy/foamy and sometime multicolored? I like the small rectangular shrimp chips that come in a bag that seem more like shrimp fries, but sometimes I just want a bunch of the big flat round kind. ( Here's an example of what I'm talking about) Chinatown/Super88 hasn't exactly been helpful.

Thanks!
