Similar concept. Mine has the key word Virtual in it. Since Virtual is a fancy word for Not Quite, I'm Not Quite inclined to disavow my offering. I think it is an improvement; and, in the immortal words of Ernest Hemingway, "What a writer in our time has to do is write what hasn't been written before or beat dead men at what they have done."
Not that lemmycaution, of whom I'm a huge fan, is anywhere near dead. What a Virtualoso! (Wonder if "virtualoso" was used in any Tron reviews...?)
