With the potential minecarts have, and maybe even an improvement to fluid dynamics (at least splash effects), anyone willing to make rollercoasters and log flume rides for dwarves? We need a carnival megaproject made. There are already a few features such as having the archery targets for the shooting game, we have clowns, we have zombies, were-beasts, and ghosts (and depending on injury/curse, even a few deformities), with a bit of modding, we can have drinks and snacks and edible cotton candy (though we can make the sales stands out of that material too); all we need now are some rides.
Let's make this happen.We can also try to make use of drawbridges inside pools to turn them into wave pools if I got another thread correct. We can make ourselves some waterparks too while at it.
EDIT:
We can make log flume rides even dorfier by instead of submerging the minecarts in pools of water, we can use either magma or captives light enough to not compromise the ride, but heavy enough or with the right build to pop like a water balloon filled with chunky salsa on contact. We can also use cats with DFHack's 'catsplosion' command to keep those pools adequately filled for a satisfying
*splash*. The only other thing to worry about there is making sure to keep the captives restrained, or the cats contained.
Another idea, inspired by Toady's recent update, Dwarven bowling. Follows similar structure as the update, but uses something more abundant than aardvarks. Again, either captives or cats.
EDIT EDIT:
Just re-read the post. You may have to empty the minecart after the ride ends (for consistency for all riders); so you may need to find a way to drain the excess water/blood/magma as well as keep the pool at the right water level for the ride.
