This mod adds panes that can connect on all three axes instead of just two. They will connect to Vanilla panes but the vanilla ones cannot wrap horizontally. 
Features
- Adds multi-directional glass panes and stained glass panes
- When a pane connects to six other blocks, right-clicking it will rotate it
- Horizontal versions can be created by rotating the recipe for the vanilla panes
FAQ
Q: Is this compatible with other mods?
A: There won't be any inherent incompatibilities since it won't conflict with other edits to panes.
Q: Does this mod support items from X mod?
A: No, since it replaces panes instead of modifying them, any mods that add drops or other things to regular panes won't apply to the new multi-directional panes.
Known Issues
- When you get right next to a series of Multidirectional Stained Glass Panes there are minor visual anomalies (either a new face is added or one is destroyed for like three square pixels)
Planned Features
- Add other panes to the game as multi-directional panes: iron bars
