its not just ludwig rob lol, theres loadsa makes like fibes and zickos i think they say they are the original acrylic shell company (zickos), lots of custom makes do it, and some not so heard of makes. but the ludwigs which are acrylic are vistalites, and come in any colour not just orange, the new ones are only orange and see-through i think but many old models are blue/green/red, and there are some way cool ones with like striped colours like red/orange/pink, and they have lights inside :) (Y)
