He's a decent mapmaker too, and author of one of the coolest maps on NUMA: Weave.
More recently, LouDog004 has taken a shining to playing some of the original Metanet levels and gradually building up his Total Game Score, to a point where he has broken into the top-20 for both level and episode total game score.
