Construct has a hilt in method for taking a told sheet and making it into a animation... And that looks like a tile sheet to me <img src="smileys/smiley1.gif" border="0" align="middle" />
Other wise I recommend google sketch up it's a 3D modelling software(there's a free copy) which allows you to take a 3d model and turn it into a 3D png sequence perfect for what your trying to do. Plus a cube is really easy to model I'm sure you can do that... <img src="smileys/smiley4.gif" border="0" align="middle" />
