Here you can see that the value of the convolution at a point, t, is the area shared by the two graphs when one is centered at the origin and the other at t.

Video Tutorial on Convolution
Video is still being worked on, thanks for your patience.
In the meantime, I found this gif online and it helps me visualize the graphical approach to convolution. If you really want to play around with this concept I have also found a sample MATLAB code which can be a little fun to tweak.
