Wouldn't all shadows look like noon in the tropics, and just be "puddles" at one's feet?
Seriously, a sperical shell doesn't work, as there is no gravity inside, and it would be difficult to keep your feet on the ground! A cylindrical shell, with a glowing central core (presumably fusion-powered), may be slowly spun on its axis, giving full-time zenithal sunshine. Moving shadow planes have been suggested as a means of providing at least twilight conditions, without the need to extinguish the fusion core. These could orbit near the core, in near-weightless conditions. There are exciting recreational possibilities, as well, for low-G mountain climbing at the endwalls, and free flight in the space "above" the living surface...
