i first started off by wanting to know what the Alteran space ship looked like, and i found what i think is an uncanny resemblance to the design of the lid from the Ark Of Truth, now obviously it's a little hard to see what i'm seeing since the resolution of this ship i had to blow up but i decided to put them up side by side and i found them to be an almost replica.

So this is the Alteran space ship that takes off within the mountain just as they leave the Ori galaxy forever.

I just found it interesting that the ship resembled the same design as the lid for the Ark itself.

If the lid were tilted just to the right view, you would see what i see, although it's not exact, the color of the ship kind has an dark blue hue to it and it looks a little space punk, like what the Destiny had on the outside of the ship, but the resemblance is there when you see the ball things on the corners of the ship as well as the giant half sphere in the middle of the ship, and if you know what the inside of the lid looks like is an giant red crystal which is located directly below the sphere on top, where the Ark had it's power directed like where the ships power is directed for lift off.

Funny enough, there are little designs outside of the ark that resemble some goa'uld designs found in their tech, but because we know that the goa'uld tech is based off of Alteran tech, this would make sense.
