Re: Sample application as showcase of Clojure DSL / Metaprogramming?
While the statement that creating any syntax is true for LISP, so for Clojure its not because of missing reader macro (The read table is currently not accessible to user programs. from http://clojure.org/reader). Nevertheless I found homoiconicity very useful. I turned my XML document (with my imagined syntax) into Clojure code which was just bunch of functions and macros (for changing the execution the control flow). It was made for my custom forms, context validations and transformations into Java objects in GWT project (unfortunately the client side still had to interpret the data structures to create froms, but the rest could be executed with Clojure on the server side). Above example resembles the ANT with the difference that I hadn't to write complicated interpreter and class hierarchy (one module less) and still gained better flexibility and maintenance in future.

Re: Sample application as showcase of Clojure DSL / Metaprogramming?
Hello Alexey, Probably, russian is your primary language? Then look here for the examples of the DSL: 1. http://my-clojure.blogspot.com/search/label/DSL -- a simple embedded DSL for the application configuration; 2. Here (http://scala.by/meetups/2011/09/10/4.html) you may get the slides of my presentation and my speech in MS Word format. It is about DSLs construction.

You might find my article useful: http://pragprog.com/magazines/2011-07/growing-a-dsl-with-clojure (Errata: http://forums.pragprog.com/forums/134/topics/9318) You can then dig into the code of stevedore: https://github.com/pallet/stevedore It's basically building an interpreter, but all of the same concepts as building a DSL.
