Single person electric quad-copter:
SD-03 SkyDrive manned flight model [en.skydrive2020.com] in Japan.
Powered paragliding [en.m.wikipedia.org] is pure exhilaration, an
autogyro [en.m.wikipedia.org] is sensible fun... now if a practical manned quad-copter, especially an electric one, can be developed...
Note: currently electric auto-gyros can only fly for about 30 minutes on a charge... so just an expensive toy... it would be loverly to get useful electric personal flying machines... drones are awesome but that’s just looking along not flying along aloft...
