Make a jump-house out of slime blocks? with fireworks shooting up from dispensers around the jumping house? (All interior) Edit - If you're trying to play in fullscreen, hit F11 when Minecraft is open, and it'll go to a full screen, and then hit F11 again to put it back into a window format. You'll notice an increase in FPS compared to just using a full screen window.
