Ahh. This brings back memories. I used to do this when I was using Adobe (Macromedia originally) FLASH back in the day. If no FLASH, show them the shitty version. HAHA. Good times.
You'd be surprised how often Flash was "the shitty version" as it was almost always bloated with long load times, inaccessible content and a lot of pointless stuff that was clearly to impress the client who comissioned it, not the poor user who wanted to find something out.
