Some of those are absolutely fantastic! The 3rd to last ("spiders") and 2nd to last ("neon") could be reworked into some interesting alien ship control room designs. I used to draw control panels onto play-blocks as an adolescent and tried to give them an aesthetic tilt. Reflecting the style of the times, they looked like R2D2 mated with Max Headroom: "B-b-b-beep, Ch-ch-chirp"
