Rain
I need to buy a second one, identical. Asymmetry irks me, I just can't seem to find room for one lava lamp.
Same here. I, too, have long wanted some proper (heavy, metal, sand-filled) speaker stands. I have a pair of crude home-made wooden stands. Ugly as they are, they do the job just fine so it's hard to justify the expense of replacing them.
Now, though, you may have provided me with two answers: where to put the lava lamps and justification for buying new speaker stands. If I buy new stands, I can use the old ones to support a pair of lava lamps.
