LKO's and Machines are 3D renders, while mine was made in MS Paint. You can download all three in the pack here
Also recently, Lin Kui Ominae made a fantastic update on his Fortress Tower.
It's a monster component tower that features SIX different upgrades!
Since its first release, it has been touched up significantly
"rendered with antialiasing and no secondary upgrade pod.
It also has improved damage frames and an active anim (with damageanim) of a glowing dome in the centre of the ringrails."
