While you won't achieve projections of your toddler sputtering "help me Tinky Winky, you're my only hope", the Litiholo Hologram Kit does allow you to make your own 3D laser holograms at home. The kit includes a "SafetyLight" laser and all the other bits required to create and view the image. But what really makes this kit usable by us hacks is their Polaroidesque "Instant Hologram Film" (a reasonable $2US per hologram) which unlike traditional holographic film does not require chemical processing, a dark room, or even vibration free hardware. The same laser is then used to view the hologram. The kit is available now and includes 20 film plates for $139US.
