I noticed the assumed disruptors on the D-4 Bird of Prey acting similarly. Freezeframing and slow-moing the HD Youtube clip, I saw the "disruptor bolts" actually closer resembled the swirling drone weapons from Stargate Atlantis
It made me wonder whether we've really been seeing what we think we've been seeing for the past 45 years of Trek. Could the "main batteries" of the D-7 cruiser in "Elaan of Troyius" have actually been firing similar? Or perhaps the Scimitar in Nemesis
? It's fun to think about.
