Well, you could do this - Create your object, be it text, a cylinder, sphere, or whatever. Set Motion to "Motion Path." Advance a couple frames. Move said object to the target destination at the last frame of the animation, and and any points to your path. Make sure that the Distance Along Path attribute is set to its maximum value, so it is at the path's end point. Open up the sequencer, and click on the little diagonal line between the first frame and the triangle at the end [the keyframe]. The properties tray will now allow you to edit the tweener. Tweener's modify how Carrara interpolates the change between keyframes. Use the popup menu to change the tweener to "Oscillate." Choose a sawtooth type wave. Change the number of oscillations to however many you wish. Set the Up Phase to 100%. This means that the keyframe repeats itself the number of times you set in #Oscillations box. Up Phase means how fast it alternates between forward and back. Since we are on sawtooth, the loop always starts from the beginning, i.e. it doesnt go forwards, reverse, forwards, reverse, etc. Sawtooths go forward, wait, forward, wait. Up Phase determines how quickly it goes through the wait, or on the sine graph, the Going Up Phase. Setting it to 100% means the change is instantaneous; once it gets to the end point, it immeadaetly repeats. Experiment with other waves for different reates of change. Some trig knowledge will make this easier. To get the light to pulsate, you do roughly the same thing with a shader - At the begining, set Glow==0, at the end, Glow==100. Change the shaders tweener to Oscillate, Sine Wave. Set the #Oscilations==#Oscillations of the moving object/s. Set Up Phase to 50%. Now the objects will fly across its path, and it will flicker on and off while moving. Note - I messed around with this, but I couldn't get the flickering to sync up with the object motion...but playing around with it should get you suitable results. Let me know if this doesnt help.
