breadcrumb and poker (usability >> accessibility?)

has anyone seen something similar to the following? or have a view.
for clarity to this audience this is a text version, we'll be using 
graphics if we use it at all.

Home | Media | Music | jazz | Pop | classic | soul | country

the poker aspect allows the user to see what other topics are siblings 
with the current one, which would be pop in this case, and reach them 
with a single click.

thanks

Jonathan
