I noticed that a few people found some of my custom kangaroo blocks useful so I thought I would start a thread where I uploaded a bunch of my useful ones. Especially visualization and K2Eng custom blocks. I hope you find them useful! Some of these are old and not maintained so your mileage may vary.
