The Scribbled Cliffs by Scottius Polke
Walk up the road until you reach the volcano, which spews out colored tubs (script credited to Desdemona Enfield). Click once or twice on the blue tub sitting in front of the volcano, and it'll rez a tub which you can ride into the sky. You can grab the tub (if you hover your cursor over the tub, your cursor will become a hand) and fling it across the sky.
The windlight setting for The Scribbled Cliffs is "[TOR] SUNRISE - Tusken"; if you use Firestorm, it will set automatically.
There were several preview posts for this one, by Quan Lavender , Ziki Questi, and Kara Trapdoor. Thanks, all of you!
