For anyone else who's interested, I've uploaded the WGT version of the Enyo sampler that I put together for mbo here: http://mikeasoft.com/~mike/tizmee/enyo-sampler.wgt

WGTs are simply zip files containing the application, its icon and a config.xml giving various bits of extra information. So if you unzip the enyo-sampler.wgt you should be able to see exactly what I've done in the config.xml file.
