beamer ornate template

Dear Lyx Developers,

I usually use latex directy (with vim&pdflatex), however I recently saw 
a presentation with an interesting design and the guy claimed to have 
used lyx. Anyway I installed it and yes: the beamer template tracks the 
sections in a top(!) bar, not a side bar. I converted to tex an searched 
the code, but not find out, how it is done!!
Can you tell me, who created this template? And do you get 
(sub-)sections into the top bar!!

Thanks,

Daniel who is grateful for any hint
