I wish there were another flight mode where I could take my spark to a certain point and then turn it on, kind of like tripod mode but where it would turn 360 degrees very slowly so that I could get a 360 video that does not make me dizzy.  
Are flight mode in the Spark programmable?

Unfortunately they are not programable.  However what you are looking to do is quite simple.  If you put your Spark in Tripod mode before doing the 360, it will make the yaw slow down so it won't go so fast and make you dizzy.  Also, just go easier on the yaw instead of going full blast.
