Tucker's arm cloaked accidentally for more than a day was probably a little more than holographic tech... :-)
True. However, you misunderstood me. I didn't say the Suliban cloak used holographic tech. In a reply, I wrote the Suliban probably got cloaking tech from the future. I only said the Romulans and possibly the Xyrillians used holographics to give the appearance of being cloaked.
