Audio/music: puredata [1] is pretty visual to start with and you can play around with things, gets away from the REPL completely. ChucK [2] and supercollider [3] require typing code into a terminal, but are feasible perhaps because of the minimal complexity of most live coding sessions.
Graphic artists have Processing [4]. REPL but with simplified grammar.
Perhaps the end-user programming future is in domain specific programming environments (R like but for different disciplines?)
