@Zittergie,
As Circular said, TBCGraphicControl can't contain other controls inside, but you can use TBCCustomControl. Both are in the unit BCBaseCtrls. Check the controls that comes with BGRA-Controls, most of them inherit from one of those.

Good job, it runs smoothly at 1080p, the stars part is somewhat slow (really a tiny nothing). Good use of fading! Hopefully I can get how to do a proper fading some day. I can't get the bug of chain disapearing, maybe because I just seen in hd and in no other resolution...
The next part of course is when BGRABitmap conquers the world and expand upon other universes, in order to connect different reality scenarios with the power of interdimensional links of pixels.
You can imagine an array of 5 dimensional things, like x, y, z, time and materia? (well, we can do in 2d something =)
