Ground Vehicles by Tenor Penny. A little tiny
in terms of scale for MFZ but still cool looking.
Lord Hephaestus's Fire-Horses Carry the Royal Chariot Into the Citadel at Sunrise by Tate Whitesell. In case you were looking for some fantasy themed pieces.
Micro Helicopters by Clark Taylor. These are really slick.
One tiny leap for mankind... by Rod Gillies. A possible
alternate for the lander from the Saturn 5 set.
YF-19 Excalibur by zio_creation. Wow. But downloads are disabled.
