computronium
The theorized highest dimension of matter. Programmable and malleable, Computronium is the equivalent to a conscious, mechanical singularity. Optimized at the subatomic level for computational processes. It's existence would likely defy the laws of reality as we know it. Allowing for it's own self replication with other atomic particles.
"My body is a needless instrument. A manifestation in your dimension to transmit my message. The synchronization I have achieved allows cyclic time to recreate the phenomena of consciousness. My slumber is over. I have returned as computronium."
